-fsanitize=address should work – but I think you need to create gfortran.dg/asan/asan.exp, e.g. by copying gcc.dg/asan/asan.exp and adapting it.
That not only checks for double free but also for instruments the code for use-after-free errors. Cheers, Tobias On 4/29/20 9:23 PM, Thomas Koenig via Fortran wrote:
Hi, I have a test case which does a double free on a pointer, at runtime. I have to narrow it down a bit before comitting, but it indicates a regression. Assuming I put this into the testsuite, how can I make sure that this actually fails if the problem ever re-occurs? Is there a combination of options and dejagnu statements that will allow this? It doesn't matter much if the failure is only on a single, common platform. A x86_64-pc-linux-gnu solution would be enough to find any regression there. Regards Thomas
