Comment:

 I can confirm this bug, and I couldn't even build TBB without getting a
 segfault.

 After some digging I found this
 https://bugzilla.mozilla.org/show_bug.cgi?id=770819 and this
 https://bugzilla.mozilla.org/show_bug.cgi?id=771569.

 I looks like a glibc bug interacts badly with a hack that Firefox pulls on
 the ELF structure (apparently to speed things up:
 http://sourceware.org/bugzilla/show_bug.cgi?id=14341#c0).

 Mozilla appears to have fixed this in 10esr
 (https://hg.mozilla.org/releases/mozilla-esr10/rev/2ffb11d8b2f8), so we
 should have a fix for this when we update to 10.0.6.

 Anyway, I am building TBB now with --disable-elf-hack to see if it fixes
 the issue.
