Bug #: 51635
Summary: [4.7 regression] ICE in in dwarf2out_finish, at
dwarf2out.c:22494 when building Firefox's libxul
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

AssignedTo: unassig...@gcc.gnu.org

testcase patch
Firefox's libxul fails to build with -flto and -g:
lto1: internal compiler error: in dwarf2out_finish, at dwarf2out.c:22494
I've delta reduced the failure to two files and then reduced the
files individually.
Here's what I have thus far:
% patch -p0 < patch
patching file Makefile
patching file test2.ii
patching file test.ii
% make
gcc -r -nostdlib test2.ii test.ii -w -std=gnu++0x -pipe -g -Os -flto
lto1: internal compiler error: in dwarf2out_finish, at dwarf2out.c:22494
Please submit a full bug report
Will keep trying to reduce the files further.
