Comment (by bradleyCPA):

 I suppose the problem lies at the intersection of gettext() usage after
 fork() and before exec() in bash [execute_cmd.c in bash source] in
 combination with setlocale() function replacement [libintl.h, "define
 setlocale libintl_setlocale", gettext-runtime/intl/setlocale.c in gettext
 source]. It seems that there must be some scenario or scenarios where
 calling into Apple's APIs in the gettext-provided setlocale() replacement
 spawns a thread so that after the fork() [in bash] calling back into
 Apple's APIs using CFLocaleCopyPreferredLanguages (or similar) in the
 gettext() call results in the forked process terminating.
