Bug ID: 428909
Summary: helgrind: need to intercept duplicate libc definitions
for Fedora 33
Product: valgrind
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: helgrind
Assignee: jsew...@acm.org
Reporter: stacy.gaikov...@windriver.com
Target Milestone: ---
SUMMARY
In this commit
(https://sourceware.org/git/?p=valgrind.git;a=commit;h=15330adf7c2471fbaa6a0818db07078d81dbff97),
PTH_FUNC was modified in order to intercept posix thread functions in both libc
and libpthread. The same fix needs to be done in helgrind/hg_intercepts.c, I
believe.
See also https://bugs.kde.org/show_bug.cgi?id=428035 for comments on musl.
STEPS TO REPRODUCE
1. On a machine running glibc v 2.32 (eg, Fedora 33), make valgrind from source
2. run helgrind vgtests
3. pth_destroy_cond fails
OBSERVED RESULT
helgrind/tests/pth_destroy_cond.stderr.out is empty.
EXPECTED RESULT
from helgrind/tests/pth_destroy_cond.stderr.exp:
---Thread-Announcement------------------------------------------

ADDITIONAL INFORMATION
If I have a fix myself, can I sumbit it? How? I notice this question also
wasn't answered on https://bugs.kde.org/show_bug.cgi?id=428035. Thanks.
