I am observing a crash within KSP_Solve for an application only after the 43rd call to KSP_Solve when building the application and PETSc in debug mode, full logs for which are attached with this email (1 MPI rank and 4 OMP threads were used, but this crash occurs with multiple MPI ranks as well ). I am also including the last few lines of the configuration for this build. This crash does not occur when building the application and PETSc in release mode.<span class="Apple-converted-space"> </span></p><p style="margin: 0px 0px 1.2em !important;">Could someone tell me what causes this crash and if anything can be done to prevent it?
