Crush on RPI Only when we are using gdb to debug #1201

Hi, I'm running a raspberry pi 4B 8GB version. When I run the program normally it runs without issue, but when I load it through gdb it crushes when running CPU_ProbePMULL(), CPU_ProbeAES() CPU_ProbeSHA1() CPU_ProbeSHA256() . I had to comment out those functions for debugging to be possible. Cryptopp is built into a shared library which my app loads on demand.

I don't know what "crush" is.

The probes are expected. If an instruction is not supported, then a SIGILL is raised and trapped to deactivate the feature.

Please ask questions on the mailing list in the future.
