Subject: malloc: Add tst-mallocfork to tests-exclude-threaded exception list
X-Git-Tag: glibc-2.43~25

malloc: Add tst-mallocfork to tests-exclude-threaded exception list

Commit 244c404ae85003f45aa491a50b6902655ee2df15 added -threaded-main and
-threaded-worker variants of several malloc tests with some exceptions.

tst-mallocfork calls fork from a signal handler, leading to sporadic
deadlocks when multi-threaded since fork is not AS-safe when
multi-threading.  This commit therefore adds tst-mallocfork to the
appropriate exception list.
