...ht their
CPU's and video cards back to spec, their problems magically went away.
I would follow this one up with those people... like Jason said, FLAC is
very cpu intensive, and if overheating would occur, it would be during a
FLAC encode/decode/verify pass.

libFLAC internals
Howdy.
I'm working on Altivec versions of some of the libFLAC functions. I figured
the best candidates would be those that had MMX/SSE/3dnow versions, and I
picked FLAC__lpc_restore_signal() to do first, since it's relatively simple.
In stepping through some runs, it appears that 'order' mod 4 is always 0. Is
that guaranteed, either by the format or by higher functions in the

That looks like a nice piece of software, but it appears to be specific to
Linux-x86, so I don't think it will be much help in profiling Altivec code....

Need AMD debugging help
To all who have an AMD + Windows based PC:
I have gotten a few similar bug reports about encoding
errors with FLAC. The common features are:
- Repeatedly encoding the same file with verify will have
verify errors some of the time (looks like aroung 50%) and
the verify errors will occur in different places each time.
- This is happening on AMD PCs running Windows. More reports
come from

Try oprofile. It's more accurate than gprof, and it doesn't require you
to recompile the source you're profiling.
