Do you have a normal testcase that is C++ which produces this symbol?

Yes, preprocessed file attached. But this bug is somewhat hard to reproduce,
I've spent about 3 hours trying to create a minimal test-case without much
success -  sometimes compilation is finished successfully, but the resulting
code is invalid. This is the most reliable test case I could come up with.

Example command line:
i686-mingw32-g++ -ftemplate-depth-100 -Wno-attributes -O0 -fno-inline -Wall -g
-mthreads -c "C:\work\FlexIDE\flex-core\tests\xml_report_formatter.i"

We also get ICEs on valid code with gcc 4.1.0 on both i686 and x86_64 both on
Linux if we compile our source with -fprofile-arcs -ftest-coverage.
When I tried to produce a precompiled (-E) file I could NOT reproduce the ICE
which made it impossible for me to file a bug report on my own. It worked
without problems with gcc 4.0.2.

I downloaded the Quick Fix and we no longer get ICEs. I have NOT checked the
quality of the coverage output produced by this patched gcc.

I think this is a dup of bug 26399 which was fixed for 4.2.0

And it is.  I had the same issue also and backporting the patch for PR 26399
fixes it for me.
