bug#11704: 24.1.50; REL_ALLOC-related segfault on GNU/Linux

[BT Templeton]

If I build Emacs with REL_ALLOC enabled on a GNU/Linux system, it
sometimes crashes with a segmentation fault apparently related to the
`real_morecore' function used in ralloc.c.

This is one backtrace I've gotten from a core dump of emacs -Q:
