@phprus is it correct that latest master (0815661) is used ?

phprus · 2021-12-15T15:37:00Z

@anton-potapov
Yes.
Segfault is present only is LTO enabled for tests and only on GCC-7.

In the discussion of PR #647, I did not check build with LTO enabled.

anton-potapov · 2021-12-15T15:48:34Z

@vlserov could you please take a look ?

phprus · 2021-12-16T18:22:12Z

Microsoft Visual Studio 2017, 2019, x86 and x64 - all test passed.

vlserov · 2021-12-17T08:03:40Z

@phprus, issue is not related to #647.
Tried to use TBB_ENABLE_IPO=ON instead of CMAKE_INTERPROCEDURAL_OPTIMIZATION=ON, all test are passed.
CMAKE_INTERPROCEDURAL_OPTIMIZATION adds IPO flags to tests as well.

phprus · 2021-12-17T08:38:14Z

@vlserov,
Yes, segfault is present only if IPO is enabled for tests.

vlserov · 2021-12-23T16:09:25Z

Tested on v2021.3 release with LTO Enable patch, issue is present.
Issue appears with GCC 7.5 and flags "-O1 -fdevirtualize -fipa-cp", and it doesn't with only "-O1" flag.
It isn't reproduced with GCC 8.1. Possible, some optimization options are conflicted with LTO.

phprus · 2022-03-05T08:43:17Z

Maybe close the issue, since the error is not reproduced on gcc-8 and newer?

isaevil · 2022-10-05T14:28:12Z

Closing since the error is not reproduced on gcc-8 and newer.
