            Bug ID: 57379
           Summary: [4.9 Regression]: Segfault in
                    invalidate_any_buried_refs (x=0x0) at
                    ../../gcc-svn/trunk/gcc/gcse.c:3850
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ubizjak at gmail dot com
            Target: alpha-linux-gnu

Created attachment 30167
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30167&action=edit
Preprocessed source

This is recent regression.

The segfault can be triggered with crosscompiler to alpha-linux-gnu, configured
with:

 "../gcc-svn/trunk/configure --target=alpha-linux-gnu --with-long-double-128"

$ ~/gcc-build-alpha/gcc/cc1 -O2 -fpreprocessed -quiet libgcc2.i -o libgcc2.s

It looks like recursion doesn't check for NULL_RTX when processing expr_list.

Thanks Daniel for the rectification.
