- 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.
As expected the draft of the C++ standard I've checked does not contain the SIGSEGV word at all. So there must be no portable way to do so. Is there an implementation specific documented way to do so with gcc?
