Bug#158371: g++-3.0: internal compiler error in expand_end_loop with -O

[Brett Viren <bviren@minos.phy.bnl.gov>]

Package: g++-3.0
Version: 1:3.0.4-12
Severity: important


I get:

  Internal compiler error in expand_end_loop, at stmt.c:2527

when compiling a class from our code.  I don't see anything
particularly wrong about the code, but it is part of a large code base
so I can't easily extract a simple example.  I post the command, its
output, the .s and .ii files at (193k):

  http://minos.phy.bnl.gov/~bviren/debian/g++-3.0-bug.tgz

I'll keep it there at least until this is closed.

Unpacking and running:

  g++-3.0 -O -g  -c CandTrack.ii -o junk.o

should reproduce the error.  Leave off the "-O", and it compiles.

The code will successfully compile with GCC 3.2.
