add suppression for helgrind/tests/tc22_exit_w_lock
|
|
|
1f061d |
|
|
|
1f061d |
Function pthread_create indirectly calls function memcpy. Helgrind
|
|
|
1f061d |
considers that memcpy is not thread safe function. For error reported
|
|
|
1f061d |
from pthread_create there is the suppression helgrind---_dl_allocate_tls
|
|
|
1f061d |
in the file glibc-2.34567-NPTL-helgrind.supp.
|
|
|
1f061d |
Since glibc version 2.23, memcpy is implemented by __mempcpy_inline.
|
|
|
1f061d |
This causes that call to memcpy from pthread_create is no longer
|
|
|
1f061d |
recognized by the suppression.
|
|
|
1f061d |
In test helgrind/tests/tc22_exit_w_lock, pthread_create is called twice,
|
|
|
1f061d |
and second call reports error, which causes failing of the test.
|
|
|
1f061d |
This patch adds suppression for glibc 2.23 and greater.
