Yes, that's nice. Yum does the same in Fedora, (And there's a version of 
Apt for Fedora too.)

Okay, then I won't report it to Redhat.

You could say I get both. :-) Running from a shell I get the same 
message as you:

    [bjorn@groucho Parafras]$ ./error

    raised STORAGE_ERROR : stack overflow (or erroneous memory access)
    [bjorn@groucho Parafras]$ ./klyv_test
    Ada 95 = morsomt => Ada 95 & morsomt

    raised STORAGE_ERROR : stack overflow (or erroneous memory access)

Running in GDB (inside GPS) I first get "Program received signal 
SIGSEGV, Segmentation fault." If I try to continue from there, 
Storage_Error is raised and the program terminates. So the SIGSEGV 
signal is translated to a Storage_Error.
