Comments on Generate SIGSEGV without undefined behaviour.
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?
