> .exe magic doesn't work with gprof. Any ideas why?

  And indeed, it doesn't work the other way round... [carrying on from your
testcase:]

dk AT mace /artimi/firmware/test> mv foo.exe foo
dk AT mace /artimi/firmware/test> rm gmon.out
dk AT mace /artimi/firmware/test> ./foo
dk AT mace /artimi/firmware/test> gprof foo.exe
foo.exe: No such file or directory
dk AT mace /artimi/firmware/test> gprof foo
Flat profile:


  Exe magic is not applied to command line arguments by the shell, otherwise
it might mangle plaintext or options: exe magic is applied when an
application tries to open a file that doesn't exist.  gprof doesn't open foo
or foo.exe; it opens gmon.out.  The exe magic would have to modify the
contents of gmon.out in accord with gprof's internal binary format to make a
difference here.  


    cheers,
