coverage mismatch

[Rajkishore Barik]

Hi,
I have been trying to use "-fprofile-generate" and "-fprofile-use" for 
some small 
bitwise C benchmarks (developed at MIT). I have a check-out of October 
2004 GCC build of 4.0 
version. It throws me "coverage mismatch error for "arcs"" saying number 
of counters is "6"
 instead of "5". How do I go around fixing these problems? In fact, 8 out 
of 15 of these benchmarks
throw me the same problem. 

Most of these benchmarks have only one module "main.c".
I compile the following way 
"gcc -O2 -fprofile-generate main.c"
"gcc -O2 -fprofile-use main.c" -- here it throws error.

Thanks for your help,
regards,
Raj
