Summary0000540: crash when exporting and downsampling
DescriptionArdour crashes when trying to export and downsample from 96000 Hz to 44100 Hz. Occasionally , the following line is repeatedly printed out the the Log window before the crash:

[ERROR]: warning, leftover frames overflowed, glitches might occur in output

othertimes the crash happens without warning.

A few months ago, on the same computer I didn't experience any problems exporting and downsampling.

Exporting without resampling works great.

GDB backtrace in additional information.

taybin - i assigned this to you only because you are probably closest to that chunk of code.

I just saw a segfault with beta19 doing something similar, exporting a region converting it from 88,200/24 to 44,100/16. The traceback was somewhat different, I'll include it here in hopes that it might help...
