beam got SIGSEGV

[Alexey Shchepin]

Hi!

 AS> Hi!  Hour ago ejabberd on jabber.ru get SIGSEGV:

[...]

 AS> BEAM was started with "+Mea r10b" options.

FYI: this bug is reproducible without this option.  Now I have few
erl_crash.dump files, which ends with something like this:

=proc_heap:<0.8173.0>
C675BF8:lHFFFFFFFF|HC2B0178

After dumping of this line, erlang process got SIGSEGV.  All core
dumps have same backtrace as in my previous message.
