Definately get away from using Thumb code with gcc-3.4.x.  There is some 
documented problems, under certain conditions, that  when an interrupt 
occurs during a Thumb function execution it can corrupt the stack.  This 
stack corruption was noted in gcc-3.3.x and was finally resolved in 
gcc-4.0.x.

I'm currently using gcc-4.0.2 and the thumb code is running fine under 
heavy interrupt usage.

BTW, I'm not using the Keil thingy.
