The following valid testcase triggers an ICE on mainline when compiled with
"gcc -O -fipa-cp -ffast-math":
===========================================
double foo(double x) { return x*x; }
double bar() { return foo(0); }
===========================================
bug.c:2: error: edge double T.0(double)->double __builtin_pow(double, double)
has no corresponding call_stmt
bug.c:2: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
Note the bug in the bug: verify_cgraph_node manages to print the first part of
the internal error, but crashes before "verify_cgraph_node failed" can be
printed.
