Subject: Add new helgrind race suppression for pth_mempcpy_false_races
X-Git-Tag: VALGRIND_3_23_0~61
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f47109d30ca319a3bcd4288803e30a473d1506d2;p=thirdparty%2Fvalgrind.git

Add new helgrind race suppression for pth_mempcpy_false_races

In glibc 2.39+ the internal __printf_buffer_write might use memmove
instead of a memcpy variant. Add an extra suppression variant using
memmove.

This makes pth_mempcpy_false_races pass again.
