[Bug gcov-profile/99443] [GCOV] No coverage with "Aborted(core dumped)"

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99443 --- Comment #1 from Andrew Pinski --- I think this is expected behavior. Aborting should not dump the coverage file at all as it should be used for an really bad unexitable situation only.

[Bug gcov-profile/99443] [GCOV] No coverage with "Aborted(core dumped)"

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99443 --- Comment #2 from Andrew Pinski --- This behavior might even be documented but I have not looked yet.

[Bug gcov-profile/99442] [GCOV] No coverage with "Segmentation fault (core dumped)"

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99442 --- Comment #1 from Andrew Pinski --- There is no way really to recover from a segfault in a manner that is suitable for all programs. The developer could set a sigv handler if they want to do any recovery from it. The library should not do it.

[Bug gcov-profile/99441] [GCOV] Wrong coverage with complex "if" condition

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99441 --- Comment #1 from Andrew Pinski --- So line 27 has a short cutting conditional included, so technically it is executed 30 times, one for each side of the &&.
