Bug in STM32 serial driver

Hi there

I discovered that high transfer loads on the UART can crash my 
application on the STM32. I wrapped up a little demo application which 
can be used to reproduce the error. See 
http://bugs.ecos.sourceware.org/show_bug.cgi?id=1000974 for details.

Can anyone with an STM3210E-EVAL board please try and see if they 
experience the same behavior? I suspect the error comes from the high 
interrupt load. Maybe the crash even results from a bug in the arch 
port. I did not yet discover where the bug comes from, but I can 
reproduce the behavior on both our custom hardware and the evaluation board.

I'd be very glad if someone else could take a look into this as well. 
Looks a bit nasty :)
