The OPAL Discussion Forum

[Rob Nagler <opal-rtnkh AT q33.us>]

Ran into another issue with Fedora 32. They've turned on code hardening (discussion) so wrappers like mpicxx automatically include flags like "-Wp,-D_GLIBCXX_ASSERTIONS", which in this case causes opal to fail to run, because of an assertion failure in stl_vector. I've included the stack below. I've worked around this by patching mpicxx & company, but I suspect it might be useful to turn on _GLIBCXX_ASSERTIONS to find some latent bugs in the code.

Cheers,

Rob
