I use MatNorm and VecNorm on A and b before I call kspsolve, and both
of them are finite. Then I use fp_trap to catch where the nan comes
from. However, it traces down to unlikely place pthread_join. The gdb
where information is given below. Can you give me some help? Thanks.

Hello everyone,
I am solving complex Ax=b with PaStix on 20 processors successfully
but failed on 24 processors. The relatively error indicated by
mat_pastix_verbose becomes "nan" for 24 processors. Where could be
wrong? Can someone give me some hints on how I can debug? Thanks.
