Program received signal SIGILL

[raulleoncz]

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?
