--- Comment #8 from Brooks Davis <brooks@FreeBSD.org> ---
Ah, I think I see what's going on.

You're inside the thread local storage (TLS) initialization, but jemlloc is
calling strtol which accesses TLS to provide an argument to strtol_l.

Calling strtol_l with a NULL locale might fix this.

(The real issue is that we shouldn't be using jemalloc for TLS, it's not
performance critical due to a pool of TLS entries being reused and having the
runtime tangled in the innards to jemalloc is complicating.)
