Package: libmimalloc3
Version: 3.0.1+ds-2+b1
Severity: important
Dear Maintainer,
/usr/bin/mtxrun (package context:amd64, Version: 2024.04.01.20240428+dfsg-2) is
crashing in an illegal instruction on my
computer. The instruction seems inside libmimalloc3 library.
Running mtxrun using gdb:
(gdb) run mtxrun
Starting program: /usr/bin/mtxrun mtxrun
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Program received signal SIGILL, Illegal instruction.
0x00007ffff7f5319a in ?? () from /lib/x86_64-linux-gnu/libmimalloc.so.3
(gdb)
Running in gdb using layout asm, the culprit instruction is RORX.
This instruction required BMI2 flags according to Intel Architecture
Sofware Developper. Apparently, this is not the case of my CPU. May be
the compilation flags of libmimalloc3 is a bit too "native" or
optimized.
# no BMI2 in the flags of my CPU.
