Subject: test/crimson/seastore/CMakeLists: tune ASan's UAR fake stack size
X-Git-Tag: testing/wip-vshankar-testing-20250812.045652-debug~10^2~1
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=b9b83498ef80860835d1748a416f9cb409b2b6d6;p=ceph-ci.git

test/crimson/seastore/CMakeLists: tune ASan's UAR fake stack size

Avoids severe slowdowns with detect_stack_use_after_return=1.
The root cause is unclear, but ASan's fake stack GC behavior is
suspected. Tuning the UAR (Use-After-Return) fake stack size
(reduced from 64KB–1MB to 64KB) helped delay the onset of the
performance degradation.
