3550-12G exception and reload when "ip flow-export"

Hi everybody,

on a WS-C3550-12G with IOS 12.1(14)EA1a i configured "ip flow-export". When I do this, the device reloads by itself, i think when it tries to export the netflow cache.

The last message is:

Unexpected exception to CPU vector 0, PC = 59EF48

-Traceback= 59EF48 22BDB8 22BFBC 1CCCD8

The contents of the crashinfo file is:

I have seen customers report this before. Please note that ip flow-export is not supported on 3550 in hardware even though CLI allows you to configure it
