LDC 1.3.x/1.4.x + LLVM 4.0/5.0 results in compiler crashes when building rdeps

[ximion]

Hi!
We just updated to LDC 1.3.x in Debian a few days ago, which is using LLVM 4 as well now (3.9 was default previously).

While LDC itself built well (bootstrap from scratch), we now get mass build failures in reverse-dependencies of LDC (status being tracked at https://release.debian.org/transitions/html/auto-ldc.html).

See for example the diet-ng build on amd64: https://buildd.debian.org/status/fetch.php?pkg=diet-ng&arch=amd64&ver=1.4.2-1%2Bb1&stamp=1504166958&raw=0

Segmentation fault

As usual, this is annoying to reproduce locally, but I did manage to do that in a pristine amd64 chroot once. To me, it appears like this might actually be a bug in LLVM.
We primarily experience this bug on amd64 and other arches, i386 seems to be safe from it.
Have you seen this with LDC before? I think I can work on generating a better backtrace, probably later next week (or at the weekend if I find the time).

To me, it appears like this might actually be a bug in LLVM.

It might well be, or it might turn out that we hit an assertion when building with them enabled – the debug info interface is not very well-documented or intuitive to use and has been a constant source of trouble (cf. all the other recent debug info issues).

Have you seen this with LDC before? I think I can work on generating a better backtrace, probably later next week (or at the weekend if I find the time).

I don't think there is an issue open for it, and personally haven't seen it before.

Okay :-)

This one fortunately turned out to be easy to reproduce locally :-)

[kinke]

Is the -O -g combo quite popular for Debian packages? These debuginfo issues are a PITA and fixing them properly might take a while.

[ximion]

This flag combination is ubiquitous in Debian packages, because it's the default. We need optimized builds (obviously) to run the software quickly, and debug information to help with debugging problems in thee post-installation.
The debug symbols are automatically stripped from the final package and placed in a -dbgsym package, to e.g. automatically retrace cŕashes etc.

[dnadlinger]

For reference, something along the lines of -O -g is also used at Weka, so it's not like it would be completely broken.

[LocutusOfBorg]

Hello, any news for this?

[kinke]

Well, an easy to reproduce, self-contained testcase is the best way to get things fixed.

[ximion]

I have uploaded LDC 1.4.0 built against LLVM 5.0 to Debian yesterday, once it clears NEW we will at least know whether that fixed anything.
This bug is currently breaking pretty much all D code in Debian (all that doesn't use GDC or requires a shared library). See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=875878

It's really annoying that something like this appears to happen so frequently, I think maybe having the CI not only build LDC and test it, but also have it build a comple of complex D projects and their dependencies would be pretty helpful.

I don't have time to create a minimized testcase for this right now, but this bug is at least 100% reproducible, and it happens on amd64 as well, so making one should not be too hard.

Correction: It actually does break everything, no matter whether there is a shared library involved or not.

At least in this case, -O -g seems to be required, so it's not like adding a few projects to CI would automatically prevent stuff like this. An older issue of yours was only uncovered due to Debian not using dub etc. So choosing a nice set of projects and cmdline flags probably isn't trivial,
especially given a rather restricted time budget.

I'd expect the projects to use an ldc and ideally an ldc-beta Travis environment and test it with their expected configuration - and us getting notified upon issues. So maybe it'd be better/more feasible for Debian to streamline the config (dub etc.) or to add/alter the CI configs of the projects to reflect the Debian one.

not really difficult to do that...

@LocutusOfBorg

not really difficult to do that...

We would need development snapshots of LDC in Debian, which we don't do and which would be very impractical for every commit. As soon as stuff has hit Debian, we already have problems, so testing this upstream would be much more helpful.

That being said... LDC 1.4.0 built against LLVM 5 does not show the issue found in this bug report. It's rather crazy and makes me thing even more that this might actually be an LLVM bug (just like the last elusive crash on armhf & co. with LDC was).
Let's wait for all rdeps on Debian to rebuild against the new LDC to confirm this is really fixed (I only built two rdeps that were failing before).
