Subject: pthread_kill would incorrectly deliver a signal to a thread even if
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=027e50a85e9e47f914a136d63596d87ab9f2bede;p=thirdparty%2Fvalgrind.git

pthread_kill would incorrectly deliver a signal to a thread even if
the thread currently had the signal blocked.  Fixed.  It _may_ also
fix some assertion failures in scheduler_sanity() in vg_scheduler.c.
