Searching for that error reveals a possibly similar issue with the
native DNS resolver in libcurl[1]. I'm not sure if this is applicable to
the case here, but it could be a general longjump/signal
handler/multithreading issue rather than something on the machine level.

Other results indicate that the error message is generated by the libc
stack checker when _FORTIFY_SOURCE is 2. Maybe there is some mishandling
going on here.

A backtrace would be helpful.
