Generate SIGSEGV without undefined behaviour.
In order to test that coredumps are generated and that they contain useful information which can be retreived with gdb I need to generate a SIGSEGV. Or anything else which causes a coredump.
The code I am using is:
int *p = nullptr; *p = 0;
Which works fine but is undefined behaviour. It might as well not generate a SIGSEGV at all.
Is there a portable way to raise that signal? And if not, is there an implementation specific documented way to do so with gcc?
