Yes, it crashed without any printout. It always crashes at the first call to KSPSolve. Currently I only has a release version of petsc lib although my program has debug version. Thanks, Qin

Absolutely nothing printed to the screen, the program just ended? Please send any output. Since it worked on linux it is likely something specific to the windows machine like lack of memory, a compiler bug, …. Does it always crash at the same place, can you run it in the debugger on the windows machine and where does it end up?
