Poking about a bit with that checkout, I find that if I do:

diff --git a/lib/verify.h b/lib/verify.h
index 6d7b961db7..e2f0cacd03 100644
--- a/lib/verify.h
+++ b/lib/verify.h

 #if 3 < __GNUC__ + (3 < __GNUC_MINOR__ + (4 <= __GNUC_PATCHLEVEL__))
 # define _GL_HAS_BUILTIN_TRAP 1
 #elif defined __has_builtin

... then there's no segmentation fault any more.
