* when cond var is destroyed, in the PRE, report an error if nwaiters > 0. * when cond_wait succeeds, get the cond var but do not create one in helgrind (it must exist if cond_wait was done). Report an error if cond not found (assuming this is caused by a destroy done while the thread was cond_wait-ing). * added a test git-svn-id: svn://svn.valgrind.org/valgrind/trunk@12721

Bugs reported after the release of 3.7.0
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This file lists bugs that were reported after 3.7.0 was released, both
|
|
in 3.7.0 and trunk, and that have not been closed. Bugs that have
|
|
been closed as "fixed" are listed in the top level NEWS file instead.
|
|
In other words they get listed here first and moved to NEWS if they
|
|
get fixed.
