[Bug middle-end/34617] New: ICE with "-fmudflap -fprofile-arcs"

[reichelt at gcc dot gnu dot org]

The following trivial testcase crashes the compiler when using the options
"-fmudflap -fprofile-arcs":

==================
void foo() {}
==================

With the C++ frontend I get the following error:

g++: Internal error: Segmentation fault (program cc1plus)
Please submit a full bug report.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

With the C frontend I get the following instead:

bug.cc: In function '_GLOBAL__I_1_foo':
bug.cc:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

The bug dates back to GCC 4.0.0 (when "-fmudflap" was introduced).
