------- Additional Comments From lothar at xcerla dot com  2003-08-04 21:37 -------
I prepared an additional case, this time with unsigned long rather than double. This should 
make clear that the bug is with -fprofile-arcs -ftest-coverage and not floating point related. 
I will attach the preprocessed file like for the first case.
