Program received signal SIGILL #1207

Closed raulleoncz closed 7 months ago

raulleoncz commented 8 months ago

Hello, I have been running some simulations on specfem2d and I'm getting the following error:

Program received signal SIGILL: Illegal instruction. Backtrace for this error: Program received signal SIGBUS: Access to an undefined portion of a memory object. Backtrace for this error:

I checked if the error could be related to the stability condition, but it is below 0.5 (0.37). I also tried a smaller DT, but the error persists. Could anyone help me identify the cause of the error?
