As far as I know, if interrupts are disabled, the thread can't be kicked.

Very bad combination ;-)
- Install and use gcc 2.95. You will save yourself from many problems.
- In principle you can't use user-space functions in realtime code, although
you may suceed with some of them. I don't think strcpy() can be used at all.
