Bug ID: 61218
Summary: lto ICE building libcilkrts with 4.9.0
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: ncahill_alt at yahoo dot com

minimal testcase
I was getting an ICE building gcc-4.9.0 with lto enabled (that is, -flto
-ffat-lto-objects), I traced it to symbol_test.o. I then reduced the
preprocessed output of symbol_test.c, this is what it reduces to:
--- bug.c ---
int main ()
{
_Cilk_spawn foo();
}
--- end bug.c ---
To cause the bug, run make or issue these commands:
gcc -fcilkplus -flto -c bug.c -o bug.o
gcc bug.o
--- output ---
lto1: internal compiler error: in streamer_get_builtin_tree, at
tree-streamer-in.c:1124
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://bugs.gentoo.org/> for instructions.
lto-wrapper: /usr/i686-pc-linux-gnu/gcc-bin/4.9.0/gcc returned 1 exit status
/usr/lib/gcc/i686-pc-linux-gnu/4.9.0/../../../../i686-pc-linux-gnu/bin/ld:
fatal error: lto-wrapper failed
collect2: error: ld returned 1 exit status
--- end output ---
The output of gcc -v is included in gccdashv.txt, and this is on i686 32-bit.
Thank you.
