Now for something more serious: I get a crash like this one: Starting KSPSolve (1/2) 0 KSP Residual norm 2.964538623545e-06 *** glibc detected *** /home/domel/build/solve-debug/ns3t10mpi: malloc(): memory corruption: 0x09258008 *** ======= Backtrace: ========= /lib/tls/i686/cmov/libc.so.6[0x5f9ff1] /lib/tls/i686/cmov/libc.so.6[0x5fcbb3] /lib/tls/i686/cmov/libc.so.6(__libc_calloc+0xa9)[0x5fe009] /home/domel/build/solve-debug/ns3t10mpi(hypre_CAlloc+0x2c)[0x8b4ea28] /home/domel/build/solve-debug/ns3t10mpi(hypre_BoomerAMGCoarsenRuge+0xb5)[0x8af2c7b] (and so on)
gdb invoked as: mpiexec -np 2 ..... -on_error_attach_debugger -display :0.0 does not display any backtrace after the crash. Any hints how to debug are highly appreciated. Dominik
