Internal compiler error in `scan_region', at except.c:2710

[Richard B. Kreckel]

Hi,

(Sorry for the last incomplete mail, if it got through...)

I have boiled down a bug in all post-2.95.2-releases (up to) snapshot
egcs-20000103 to a few lines of code, attached below.  It happens as soon
as you switch on optimization.  Does anybody know what's going wrong?

Regards
     -rbk.
