Re: Bug of g77-3.0

["Tim Prince" <tprince at computer dot org>]

log() is determined by the library you use, not by gcc.  With glibc (usually
installed in linux), the version of log() will depend on the optimization
level you have chosen.  This would be a gcc bug only if some combination of
circumstances led to stack overflow, for example.  gcc-3.0 is obsolescent,
many people may not have the exact version available to test.  We would be
stabbing in the dark without more detailed information; at least the screen
output which you have when compiling 'g77 -v ....'
