            Bug ID: 59662
           Summary: wine-mono: ASan gets triggered after commit 34a8563df.
           Product: Wine

          Hardware: x86-64
                OS: Linux

          Severity: normal

mscoree_comtest_asan.txt

Since a few days I receive in gitlab, with a modified tree to
run PE ASan enabled binaries, reports from loadpath.exe, csc.exe and mcs.exe.

They all show as last frame `copy_stack_data_internal` with a memcpy.

I was able to reproduce it with a local tree too.
If I revert following patch ASan stays silent:
34a8563df2b "mscoree: Use coop-aware thread attach functions."

Attach file shows a mscoree:comtest run,
with contents of wine-mono-11.0.0-dbgsym.tar.xz put into the prefix.
