[Bug middle-end/35696] Segmentation fault



------- Comment #5 from sam dot hendley at plymouthsystems dot com  2008-07-21 13:51 -------
Hello, I would like to report that I have had the same type of issue. I run
into this issue only when compiling with the coverage flags turned on. Here is
the output (inlcuding the location and version of g++):

Compiling PositionEstimator.cpp with g++ (for coverage)

Whats really strange about this error is that a tiny source update resolves the
problem for that file but causes a previously fine file to have a similar
issue. If I move the call to "FloatEqual" out of the if block it works without
a problem. Also if I remove the -fstack-protector flags it works as well. So
I'm pretty sure it has to do with the -fstack-protector flag. However if I add
the -fno-stack-protector flag the same sort of problem can pop up in a totally
different file. I had this same problem with a previous file and adding a
single new line into the file fixed the compilation.
