To: gcc-bugs
when compiling :
/Develop/mainline_parallel/gcc/gcc/testsuite/gcc.c-torture/execute/comp-goto-1.c
-w -O1 -ftree-parallelize-loops=4
We get compiler error during verify_flow_info
comp-goto-1.c:57: error: label
sim_base_addr has incorrect context in bb 8
The context for sim_base_addr is the new outlined function,
simulator_kernel._loopfn.0 and not simulator_kernel as expected.

A bit different testcase, crashes on x86_64-pc-linux-gnu, r165719
----- testcase.c -----
void
foo (void **a, int i)
{
while (i--)
a[i] = &&label;
label:;
}
----------------------
$ gcc -O -ftree-parallelize-loops=2 testcase.c
testcase.c: In function 'foo':
testcase.c:2:1: error: label
label has incorrect context in bb 6testcase.c:2:1: internal compiler error:
verify_flow_info failed
Please submit a full bug report,
with preprocessed source if appropriate.
