I didn't check the values of each register. The error messages (when
running gcc) are the same in that the "unsupported in 0x06" is always
there (except cc1). The "invalid opcode at eip=bcc7" is also always there
(except ccc1).

The environment settings and the corefile are shown below. The programs 
run are gcc -v, gcc, cc1, info  - in the order shown.

As shown in the dump for cc1, the error is different - Segmentation
violation in pointer 0x0046e66c at d8:b4cd5. The unsupported int 0x06
error message is not given for cc1. For the other programs run, the
unsupported int 0x06 error message is there.
