We cannot do anything without a reproducer.  See http://gcc.gnu.org/bugs.html.

However, a segfault at runtime on several platforms with -O2 and not -O1 may
hint at an aliasing problem in the code.  You could try to recompile everything
with -O2 -fno-strict-aliasing and see what happens.  Read the -fstrict-aliasing
entry in the manual, section Optimize Options, for more information.
