Description Peter Soetens 2006-07-12 13:02:16 UTC 
Full version string:
g++-4.1 (GCC) 4.1.2 20060708 (prerelease) (Ubuntu 4.1.1-8ubuntu1)
Same problem exists in Debian 'etch'.

The error message after the location of the crash is:
/usr/include/boost/spirit/core/composite/actions.hpp:106: internal compiler error: in expand_expr_addr_expr_1, at expr.c:6336

It only occurs using the -O1 and -O2 flags, but succeeds in compiling using -O0 or -O3. No other flags need to be given to trigger this crash.

Older compiler versions (4.0,3.4,3.3...) do not have this bug.

Preprocessed code follows...

After unzipping, compile this file using:

$ g++-4.1 -c attachment.ii -O2 -o attachment.o
Comment 2 Wolfgang Bangerth 2006-07-18 14:03:21 UTC 
Confirmed, though the testcase is huge and the error message atrocious.
Someone will have to take the time to reduce something smaller out of
this whole boost mess...

Comment 4 Andrew Pinski 2006-10-19 18:06:36 UTC 
This is most likely a dup of bug 28116 anyways.
Comment 5 Richard Biener 2007-02-03 13:13:06 UTC 
I cannot reproduce this with either current 4.1 branch head nor g++ (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21).
Comment 6 Andrew Pinski 2007-08-24 00:24:50 UTC 
Yes this is a dup of PR 28116.
