Crash in typescript using nodejs 16 on ppcle #38521

Flarna · 2021-05-03T16:08:21Z

Version: 16.0.0
Platform: Linux ls-ub-lf40a2dv 4.4.0-200-generic doc: update AUTHORS file, add tool for doing it #232-Ubuntu SMP Wed Jan 13 10:17:10 UTC 2021 ppc64le ppc64le ppc64le GNU/Linux
Subsystem: @nodejs/v8

What steps will reproduce the bug?

building a project (unfortunately closed source) using typescript 4.2.4

Update: Seems to happen with other projects, e.g. building typescript itself

How often does it reproduce? Is there a required condition?

always, no special condition besides using PPCLE (no problem on windows, linux x86, linux arm).

What is the expected behavior?

building works also on PPCLE

What do you see instead?

/home/labuser/repo/node/proj/node_modules/typescript/lib/tsc.js:88057

Additional information

If I attach the debugger problem is gone.
If I add typeof(node.slice) (which should be a not in my opinion) just before the line causing the TypeError it no longer occurs but a similar TypeError happens at another place.
If I add also typeof() checks at the next two such locations I finally end up in a segmentation fault with a quite small callstack:

#0  0x00000000115dd9b4 in Builtins_LoadIC_Megamorphic ()
#1  0x00000e8ec1d600e0 in ?? ()

The text was updated successfully, but these errors were encountered:

/cc @nodejs/platform-ppc

mhdawson · 2021-05-03T21:55:16Z

@miladfarca are there some options you could recommend to disable V8 optimizations to see if it might be related to code being generated?

miladfarca · 2021-05-04T01:22:34Z

--jitless can be used to avoid generating code: i.e:

node --jitless npm ...

will look into the details on why it is segfaulting on ppc.

Flarna · 2021-05-04T08:54:50Z

I can confirm that --jitless avoids the crash.

miladfarca · 2021-05-04T13:14:54Z

@Flarna Thanks for confirming. Would you also be able to use the v16.0.0 node binary from this nightly build and check if the problem still exists? (without using --jitless)

https://nodejs.org/download/nightly/v16.0.0-nightly202102126ea9af9906/

PPC file will be: https://nodejs.org/download/nightly/v16.0.0-nightly202102126ea9af9906/node-v16.0.0-nightly202102126ea9af9906-linux-ppc64le.tar.gz

Flarna · 2021-05-04T13:39:36Z

@miladfarca This version looks good.

Tried also the next newer version v16.0.0-nightly2021021388d9268d08 => this one shows the problem

john-yan · 2021-05-06T15:21:33Z

Debug build is not able to compile at the moment. I submitted another PR at #38571 so this might take longer. @targos Would you be able to help on the gyp/GN scraper issue?

gyakovlev · 2021-05-07T04:53:44Z

can confirm segfault while building qtwebengine/chromium typescript parts on ppc64le with 16.1.0

gyakovlev · 2021-05-07T06:05:37Z

I can't reproduce with debug build of node (with #38571 applied)

gyakovlev · 2021-05-07T07:13:36Z

ok I've tried building with -O0 (default for debug unoptimized build), -Og , and -O2 for BUILDTYPE=Debug it does SIGTRAP

I found the issue. It was caused by trampoline pool emission during deopt exit table generation. Deoptimizer expects deopt exits to be continuous. However, trampoline pool breaks this underlining assumption. I will submit a CL to fix this soon.
