Version: 0.5.8-1
Severity: normal

Hi,

thanks for maintaining rakarrack.

If I select rock amp from the first bank while effects are enabled, rakarrack
crashes. There are a few other effects that also lead to a crash, e.g. metal
amp, also from the first bank. Here's the output that I get:

The same architecture and release and the same problem. I didn't have 
this problem with older versions.

Hi,

just did a little bit of debugging, looks like Convolotron is to blame, as it 
accesses the buffer beyond its end in src/Convolotron.C +181.
In line 198, there's the corresponding off by one. I think line 190 / 191 can 
also result in an off by one access.

Sadly fixing these two places didn't seem to help :(. Maybe that's a starting 
point nonetheless.

Cheers,
  Stefan.

Hi,

I've forwarded this issue to rakarrack upstream who gave me a possible cause
for the crash.

Please read and tell me if it helps:

https://sourceforge.net/tracker/index.php?func=detail&aid=3322112&group_id=215888&atid=1035482

I know it's not a definive fix, but i think it can be useful now.

Feedbacks after applying upstream's suggestions are very welcome :)

Regards,

Yes, changing the convolotron settings, everything works for me now.

Btw, I've been in contact with upstream already, the off-by-one's are already
fixed in git. Sorry for not following up earlier on.

Cheers and thanks again for maintaining this package,
    Stefan.
