Auto merge of #44525 - aidanhs:aphs-no-null-deref, r=alexcrichton

Correctly bubble up errors from libbacktrace

Previously the first part of this code didn't check for a null pointer and blindly passed it back down, causing a segfault if libbacktrace failed to initialise. I've changed this to check and bubble up the error if relevant.
