@yangbai90 I think this problem is about memory.

[bbsy789]

I modify the CMakeLists.txt.Add some args-fsanitize=undefined,address and change other args-O2->-Og,-Werror->none to CMAKE_CXX_FLAGS. I use this command find / -name "libasan.so" to get the location of "libasan.so", then

LD_PRELOAD=/usr/lib/gcc/x86_64-linux-gnu/5/libasan.so ./asfem --version. The result following:

liujinmei@ln0:~/AsFem/bin$ LD_PRELOAD=/thfs1/home/liujinmei/software/gcc/gcc12.2/lib64/libasan.so ./asfem --version

cpu:arrch64 system:ubuntu compiler:gcc12.2 mpi: mpich/mpi-x-gcc9.3.0 petsc:3.17.2 finded this issue.

[bbsy789]

The issue's reason may be found, in which the openmpi and petsc must be compiled by the same compiler's version. This issue has been solved. Thanks for your help!
