- Well, there is a trap called in that case and an official guru number

- Yes, in my case ixemul has no swap-code. So that is not the source
- of the trouble.

- In fact I have donwloaded gcc 2.7.2 and ixemul 43, and that guru
- disappeared too (it seems so), but I must still run cc1, as and ld
- with no swap-code.
-
- I'd like to know precisely why it crashes with gcc2.7.0 and not with
- 2.7.2... is it due to the autostackextend or due to the new version
- of ixemul ? but for now I'm quite happy since it seems to work well.
- (I need to do some more testing to be fully happy)
