I have just successfully compiled ICE (Incremental Configuration Environment)
using g++ 2.8.1. It was a difficult due to my limited hands on C++ expirience,
the complexity of the application (class structure) and repeated "internal
compiler" errors. When I ran the test suite most test passed, but all that
involved I/O failed with seg faults. I am speculating that they are being caused
by a linkage problem.
In all cases the internal compiler errors reported were eliminated by correcting
what this C++ neophites eyes saw as erroneous syntactical constructs. The parser
seems to have at least an existential crisis if not a pyscotic espisode dealing
with errors that are almost right, primarily scope and argument issues.
I am sticking with 2.8.1 for now. My confidence in this release went up
signifcantly when the fix for the X11 server crashes turn out to be a missing
"volatile" key word in the kernel source. Everything including the kernel seems
to run faster after compiling with this version.
Being familiar with cryptic, confusing and misleading error messages certainly
has helped me, but I have questioned my sanity more than I usually do. I am also
interested in egcs and looking forward to hearing other peoples, err I mean
programmers, expirience and perspective

Amen.
