No.  The bug was in the library function that _gathers_ the profile
info.  This function runs in the program being profiled; Gprof never
calls it.

Gprof is just a simple BFD application that translates EIP values into
symbol names using the symbol table, and then formats them nicely for
output.  It doesn't itself mess with timing and such likes.
