Sorry, I forget to add this.

Hello Alexander,
thanks for the additional information. I can replicate
the crash exhibited by your original testcase on gcc
3.3 prerelease and mainline (20030509). Thanks,
Dara

Hello,
you don't mention a platform in your bug report, nor do you give the
exact error message. Both are essential to tracking down your bug.
Could you please add them (just replying to this message will do so).
Also, if possible, can you try your testcase on gcc 3.2.3? Thanks,
Dara
