The patch I meant here was the patch you got from bkbits to obtain the
latest source from 0.98.5.

Arun,
I used the patch you sent and I seem to get 2 errors (8 errors in total)
more than yours.

The SP seems to get corrupted between signals. 

Stack pointer changed from 0x7fbfffef5f to 0x7fbfffed4f between signals
