Re: [Perfparse-users] Compiling PP 0.105.5 on Fedora Core 3

[Ben C. <bcl...@pe...>]

Nick,

Very glad it does work.  My guess is that your version of gcc, which has 
only be released a short time, completed some very deep checking.  This 
is where this warning was found.  We know the code works, but we will 
have to look into it further to find out what gcc has found.

Or possibly being the latest gcc, it's a bug in gcc.  But thankfully I 
think this unlikely :)

Sorry about the deletion problem.  Know bug.  Will be fixed on next version.

Please keep us informed of any PerfParse problems and solution you find, 
and enjoy the product.

Kind regards,

Ben Clewett.
