Hello,

I recently tried to use gprof on a sparc-solaris system and I noticed that it when compiled for sparc-solaris, gprof was unable to process gmon.out files which format are "magic".

Here are the tests I did:
I used binutils 2.15.
1) I compiled libiberty, bfd and gprof on a sparc-solaris system and did the same on a i686-pc
2) I compiled the program to be tested for i486 and run it on a i486-pc.
3.a) I executed gprof on the i686-pc "gprof --file-format=magic my_file" -> OK no prob; this works normally. 3.b) I did the same on the sparc "gprof --file-format=magic my_file" and received this message:
        "gmon.out: Error 0"

I tried several versions of binutils and still obtained the same error on solaris althought everything went well on the pc. The problem is that I have to use only the sparc to do my job...

Thanks and good luck :)
Christophe G.
