I think my code only showed a dlopen() with a single call, but my backtrace shows that it attempts to load the library twice (with caught exceptions), followed by a possible success the third time, then the glibmm init and segfault. I don't know why the library load is failing. Since I did a stack allocation instead, I'd think that memory would become invalid if the library unloaded before the glibmm init.
I'd mainly have to play with it in gdb more to see what's happening. nos...@kota.moe might've done more debugging than I did.
