Thumb/exceptions in program


Hello,
I have a strange problem with thumb.
I can run my program without any problem using ARM 32 bit instruction.
I get exceptions (abort data) if I compile everything for thumb. I find
that the exception may accure in the IRQ routines. The command is:
stmdb   sp!, {r0, r1, r2, r3, r4, r5}

What can this be?

System:
latest ecos cvs, gcc (tried 3.2.1, 3.3.3, 3.3.4), binutils 2.14.91 and
latest cvs.

Regards,
 Sven Rehfuß
