boomeramg crash with openmp

[bobby-philip]

Hi:

I'm getting the following crash with hypre when I turn on OpenMP. I'm running hypre 2.18.2 compiled with intel, MPI is mpich, and OMP_NUM_THREADS=16 and I'm running on KNL's

hypre is configured with" ./configure --enable-mixedint --with-openmp

======= Backtrace: ========= (hypre_BoomerAMGSetup+0x26a2)[0x3982ef2] double free or corruption (fasttop): 0x00000000056a6420 *** free(): invalid next size (normal): 0x0000000006ad4f60 ***

gdb backtrace gives:

Hi, How big is the problem you are running, and how many MPI tasks? Thanks Ulrike
