Subject: Call real pthread_sigmask instead of its wrapper in start_mark_threads
X-Git-Tag: v8.0.2~100
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=45b17c2c3d54a4d187f20bb548826b98f53771e2;p=gc

Call real pthread_sigmask instead of its wrapper in start_mark_threads
(fix of commit 95947bdc5)

The wrapper itself does not do anything useful in this case.

* pthread_support.c [PARALLEL_MARK && !NO_MARKER_SPECIAL_SIGMASK]
(GC_start_mark_threads_inner): Call REAL_FUNC(pthread_sigmask) instead
of pthread_sigmask.
