[petsc-users] Anyone meet mumps crash on AIX?

[Gong Ding]

Hi,
I am testing my code on AIX.
petsc 3.2 with MUMPS 4.10 ALWAYS crash, both serial and parallel, with ERROR: 0031-250  task 0: Segmentation fault.
However, other direct solver seems ok, i.e. superlu.

The core file was checked by gdb, but only littel information: 
Program terminated with signal 11, Segmentation fault.
#0  0x000000010150d8ec in dmumps_462 ()

I had checked the code with valgrind on Linux/AMD64, which also reported some memory problem (but never crash)
