I don't know where else to post, so I thought I would do it here. If there's a better place, please tell me.
Found an STL bug that I thought I would report in std::forward_list. The erase_after does NOT return the next element after the one being erased. It returns the first element in the list. This caused my program to re-traverse the list and caused unexpected things to happen.
particleIter = b.content.erase_after(lastIter); // IMPLEMENTATION BUG: Doesn't return element after one erased. Returns first element in list instead
particleIter = std::next(lastIter); // workaround
If this truly is an STL bug (a bug in the library and not the compiler) then you should report it to GNU (Linux) or Microsoft (Windows).
