That... does not look like any specific problem, it looks like memory
corruption, because it detects an error inside malloc() and then hangs trying
to report it which involves some init-once dlopening a library hitting a
deadlock on a mutex. Something that I would describe as "wtf".

Unfortunately this doesn't tell much. But since you say it does not happen when
ran under Valgrind, it might involve a race which leads to e.g. use of freed
memory or whatever corrupting memory.

Gaah...
