Very many thanks to Janice for identifing the patch to the 3.3 branch that
appears to have resolved this issue:
2003-10-03 Zdenek Dvorak <rakdver@atrey.karlin.mff.cuni.cz>
PR/11883
* cfgloop.c (flow_loops_find): Fix handling of abnormal edges.
Given that PR optimization/11883 was also an ICE in flow_loops_find, it looks
like this problem was a duplicate, and was correctly fixed by Zdenek's change.
Given I'm currently unable to reproduce this failure against either the current
3.3 branch or mainline (though I can with gcc 3.3.1), I'm closing this PR as
fixed resolved. Many thanks again to Zdenek and Janice.
