malloc is not thread-safe in glibc

[Michael Truog]

Wouldn't this malloc glibc bug affect Erlang?
http://sourceware.org/bugzilla/show_bug.cgi?id=6952

The glibc maintainer works for RedHat and they have an update for RHEL. 
The ptmalloc3 in the bug report is here:

Since it is architecture dependent, it wouldn't be a problem for
everyone.  Just was surprised to see it.
