[valgrind] [Bug 486093] -Wstrict-aliasing in tests
https://bugs.kde.org/show_bug.cgi?id=486093
--- Comment #1 from Sam James ---
As a workaround, we're building tests with:
```
emake CFLAGS="${CFLAGS} -fno-strict-aliasing" LDFLAGS="${LDFLAGS}
-Wl,-z,notext" check
```
for now.

[valgrind] [Bug 486093] New: -Wstrict-aliasing in tests
https://bugs.kde.org/show_bug.cgi?id=486093
Bug ID: 486093
Summary: -Wstrict-aliasing in tests
Classification: Developer tools
Product: valgrind
Version: 3.22 GIT
Platform: Other
OS: Other
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: s...@gentoo.org
Target Milestone: ---
THere's a lot of -Wstrict-aliasing instances in the testsuite. In Gentoo, we
try to recommend people to use -Werror=strict-aliasing
-Werror=lto-type-mismatch -Werror=some-other-bits when using LTO to help find
likely runtime problems (Valgrind isn't LTO-compaitble for other reasons but
that's neither here nor there for this).
When building Valgrind with such, we get:

https://bugs.kde.org/show_bug.cgi?id=475652 Bug ID: 475652 Summary: Missing suppression for __wcsncpy_avx2 (strncpy-avx2.S:308)? Classification: Developer tools Product: valgrind Version: 3.22 GIT Platform: Other OS: Other Status: REPORTED Severity: normal Priority: NOR Component: memcheck Assignee: jsew...@acm.org Reporter: s...@gentoo.org Target Milestone: --- SUMMARY Invalid read found in __wcsncpy_avx2 (strncpy-avx2.S:308) when running Python software, may need a suppression as it's from glibc. STEPS TO REPRODUCE 1. Run 'valgrind --trace-children=yes emerge -pvO bash' on a Gentoo Linux system 2. I suspect that it's related to a recent change in Gentoo where we allowed glibc's autodetection of x86 ISA for runtime loading OBSERVED RESULT ``` $ valgrind --trace-children=yes emerge -pvO bash ==1273477== Memcheck, a memory error detector ==1273477== Copyright (C) 2002-2022, and GNU GPL'd, by Julian Seward et al. ==1273477== Using Valgrind-3.21.0 and LibVEX; rerun with -h for copyright info ==1273477== Command: /usr/bin/emerge -pvO bash ==1273477== ==1273477== Memcheck, a memory error detector ==1273477== Copyright (C) 2002-2022, and GNU GPL'd, by Julian Seward et al. ==1273477== Using Valgrind-3.21.0 and LibVEX; rerun with -h for copyright info ==1273477== Command: /usr/lib/python-exec/python3.12/emerge -pvO bash ==1273477== ==1273477== Invalid read of size 32 ==1273477==at 0x5038C93: __wcsncpy_avx2 (strncpy-avx2.S:308) ==1273477==by 0x4B209F3: UnknownInlinedFun (wchar2.h:81) ==1273477==by 0x4B209F3: _Py_wrealpath (fileutils.c:2130) ==1273477==by 0x4B18540: _PyPathConfig_ComputeSysPath0.constprop.0 (pathconfig.c:495) ==1273477==by 0x4B17D6C: UnknownInlinedFun (main.c:584) ==1273477==by 0x4B17D6C: Py_RunMain (main.c:689) ==1273477==by 0x4AD59FB: Py_BytesMain (main.c:743) ==1273477==by 0x4F05346: (below main) (libc_start_call_main.h:58) ==1273477== Address 0x5581be0 is 20 bytes after a block of size 156 alloc'd ==1273477==at 0x4840958: malloc (vg_replace_malloc.c:431) ==1273477==by 0x4AD7116: decode_current_locale (fileutils.c:482) ==1273477==by 0x4AD5988: Py_DecodeLocale (fileutils.c:664) ==1273477==by 0x4B209CE: _Py_wrealpath (fileutils.c:2119) ==1273477==by 0x4B18540: _PyPathConfig_ComputeSysPath0.constprop.0 (pathconfig.c:495) ==1273477==by 0x4B17D6C: UnknownInlinedFun (main.c:584) ==1273477==by 0x4B17D6C: Py_RunMain (main.c:689) ==1273477==by 0x4AD59FB: Py_BytesMain (main.c:743) ==1273477==by 0x4F05346: (below main) (libc_start_call_main.h:58) ==1273477== --1273477-- WARNING: unhandled amd64-linux syscall: 441 --1273477-- You may be able to write your own handler. --1273477-- Read the file README_MISSING_SYSCALL_OR_IOCTL. --1273477-- Nevertheless we consider this a bug.
