Public bug reported:
Hi,
While running the GCC testsuite with qemu-6.0 as simulator, I noticed
several errors in the hwasan testsuite (output pattern tests).
I am attaching:
bitfield-2.exe
ld-linux-aarch64.so.1
libc.so.6
libdl.so.2
libhwasan.so.0
libm.so.6
libpthread.so.0
librt.so.1
The testcase can be executed via:
qemu-aarch64 -L . bitfield-2.exe
it currently generates:
HWAddressSanitizer:DEADLYSIGNAL

You missed including libstdc++.so.6.
I ran with whatever libstdc++ I had lying around.
With qemu head, this terminates with
~/qemu/bld/qemu-aarch64 -L . ./bitfield-2.exe
*** stack smashing detected ***: terminated
qemu: uncaught target signal 6 (Aborted) - core dumped
Aborted
I suspect the relevant MTE portion of this bug report
to be a duplicate of a kasan bug, the fix for which did
not make 6.0, but has since been committed as 09641ef93112.

Sorry, I didn't think about rpath when I tried to execute what I had extracted.
Here are the additional libstdc++.so.6 and libgcc_s.so.1.
I am using a more recent qemu version than 6.0, almost head:
