FS#11010 - H300 - Illegal Insruction halt in FFT Plugin

FFT Plugin

Found in r24645

Plugin causes

at 000000002

After a variable amount of time viewing the plugin, from a few seconds to nearly a minute, haven’t found any action that causes or prevents it yet but still trying.

WFM and no more responses from the poster since it was suggested this was fixed.

Tried some MR3 files (I normally use ogg) no difference - it was a long shor anyway.

The adress suggests a null pointer dereference AFAIK and illinstr suggests it was trying to execute whatever is at 0 so maybe a null function pointer.
It would be interesting if this happens in the sim too to se a backtrace of the crash.

The fft produces n/2+1 complex results but only n/2 output bins were allocated, so it would overwrite the buffer by one, clobbering adjacent data. I took care of that, so this *could* be fixed.
