I'm not sure if you refer to the compilation crashing or your program
crashing on execution. It seems this latter one.

This is typical of dangling pointers. I.e. you're accessing deallocated
memory. Are you managing some heap memory by hand? If so, I'd suggest using
gdb to get backtraces and/or GNAT.Debug_Pools to aid in the diagnose (if
you're using GNAT obviously) as a first step.
