Bug ID: 58723
Summary: ICE in lto_output_edge, at lto-cgraph.c:300 for
OpenMP's simd reduction
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: lto

Delta reduced C++ test case
That's with gcc version 4.9.0 20131014 (experimental) [trunk revision 203511]
(GCC) on an x86-64-gnu-linux system.
$ g++ -std=c++11 -O1 -flto -fopenmp testcase20.ii
testcase20.ii:40:1: internal compiler error: in lto_output_edge, at
lto-cgraph.c:300
} // namespace std
^
Please submit a full bug report,
It works when compiled without -fopenmp. The only OpenMP code is:
#pragma omp simd reduction(+:area)
for (int yi = 0; yi < count; ++yi)
...
(where delta has removed the "area" assignment.)
