ASAN:SIGSEGV while building docs using default branch

[Ben Abbott]

I’ve been encountering ASAN:SIGSEGV frequently, but this is the first time I’ve 
seen any debug info.

This started happening in the last two weeks. Unfortunately, I don’t know what 
changed to trigger this. I’ve tried updating to older revisions, but the 
problems persists. Thus, I assume that either my system’s Xcode was updated, or 
something related to my Fink package manager was updated.

Does anyone have a thought on how I might isolate the problem?
