I think this is a dup of bug 32197.

After this ping, I tried on the same machine, with gcov off, and it worked.
However, it also worked by not using ccache (it seems that on this machine, CC
and CXX are environment variables mapping to ccache). Perhaps that is the real
issue? If I set
 unset CC
 unset CXX
 cd build
 rm -rf *
 cmake .. && make

Then I achieve success, even with gcov enabled...

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++):

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.

The testcase in comment #1 works for me with 4.3 and 4.4
