[Gwc-general] Segfault during denoise.

[Gottfried N. <Got...@gm...>]

Hi,

I tried to compile and run gwc-0.19-10 and gwc-0.19-9. First I tried 0.19-10. 
On my system the audio playback did not work. I tried play a .wav file: 
silence. The cursor did not move. No difference between OSS and Alsa.

Then I compiled 0.19-9. I can play the .wav file. I tried to declick. It 
works.
I tried to denoise, picked a sound sample, clicked on the denoise button: 
segmentation fault. In the debugger I found that the segfault occured  in 
denoise.c at line 422.  This is really strange. Just for fun, I reduced the 
size of DENOISE_MAX_FFT to 16384. Now it works. This is even stranger. 

Could someone please explain what is going on there?

My system runs under SuSE Linux 8.2 (glibc 2.3.2, gcc 3.3.1, fftw 2.1.3).

The meschach configure script assumes that the current directory is in the 
PATH. This is not always true.
Lines like
DEFS="$DEFS -DD_MACHEPS=`macheps`"
should be
DEFS="$DEFS -DD_MACHEPS=`./macheps`"

Thanks,
Gottfried
