Subject: [ECOS] solution thumb/exceptions
Organization: B2motion GmbH

Hi,
a few days ago I asked for help, because my application crashes in thumb
mode. The operator "new" throws an exception.
The problem is the optimization flag -O2. If I compile the toolchain
and/or application with -O2 I get the crahes. The compiler generates
code which is buggy (modify the stack before decrementing it). It is a
known problem of gcc 3.2.1 - 3.4.1.
Compiling all with -O1 is OK.

Regards,
 Sven Rehfuß
