Version:           2.0.0 (using KDE KDE 3.1)
Installed from:    Unspecified
Compiler:          gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5) 
OS:          Linux

Redhat 9, gcc 3.2.2

A test I'm performing is clean in 1.9.6 but seems to cause a crash
in 2.0.0.  The bug in the application is apparently deep in a Fourier
Transform library which, in an attempt to be hyper efficient, is doing
some funky memory alignment stuff.  The code for the FFT library is
macro-strewn and pretty opaque (FFTW-3.0) so I can't quite point to the
exact point of the problem, but it appears to be related to some blocks
lost when an re-alignment was done.

There may well be SSE code involved here, since FFTW does try to use
the facilities of any machine's CPU (P4 in this case) vector 
capabilities.

Following: 1. valgrind 2.0.0 output with -v
           2. valgrind 1.9.6 output with -v --leak-check
