Subject: qa: suppress false positive delete map mismatch errors
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=ae9ae0353e68543b4d6beace2767fb7ba046aa1b;p=ceph.git

qa: suppress false positive delete map mismatch errors

Valgrind reports "Mismatched free() / delete / delete []" errors during
OSD startup.

Standard library containers (like std::map) correctly call delete, but
Valgrind falsely interprets this as a call to delete[] because GCC 14
folds the identical aligned delete operators into a single symbol. This
causes Valgrind to flag a mismatch against the non-array allocation.
