Bug ID: 375806
Summary: Test helgrind/tests/tc22_exit_w_lock fails with glibc
2.24
Product: valgrind
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: helgrind
Assignee: jsew...@acm.org
Reporter: tamara.vlaho...@imgtec.com
Target Milestone: ---
Created attachment 103737
--> https://bugs.kde.org/attachment.cgi?id=103737&action=edit
New suppresion
Function pthread_create indirectly calls function memcpy. Helgrind considers
that memcpy is not thread safe function. For error reported from pthread_create
there is the suppresion helgrind---_dl_allocate_tls in the file
glibc-2.34567-NPTL-helgrind.supp.
Since glibc version 2.23 memcpy is implemented by __mempcpy_inline. This causes
that call to memcpy from pthread_create is no longer recognized by suppression.
In test helgrind/tests/tc22_exit_w_lock, pthread_create is called twice, and
second call reports error, which causes failing of test.
Attached patch adds suppression for glibc 2.23 and grater.
