Margarita Manterola, is the linked debian bug similar to what you reported earlier today on IRC?

The mentioned trivial reproducer on Debian, seems to succeed on Ubuntu, e.g.:
It's easier to reproduce than that:
 $ /libx32/ld-linux-x32.so.2
 Segmentation fault (core dumped)

Does not fail with core dump on up to date Trusty.
