Compiler goes into infinite loop when compiling Boost::Spirit programs

Description of problem:
Certain rule constructions done with Boost::spirit (www.boost.org) cause g++ 3.2.3 to go into an infinite loop.
Simple example (requires nothing more than boost libraries):
using namespace boost::spirit;
rule<> imap_append, imap_mailbox, imap_flag_list, imap_date_time,
>> ' ' >> imap_mailbox
>> !( ' ' >> imap_flag_list)
>> !( ' ' >> imap_date_time)
>> ' ' >> imap_literal
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Enter the program shown in description
2. Compile with "g++ sample.cc"
Actual Results: Compiler goes into infinite loop
Expected Results: compile
I have gentoo with gcc 3.3.6, and Fedora core 4 with gcc 4.0.1. They compile this code just fine.
Please preprocess that (g++ -E sample.cc -o sample.ii) and attach it here.
As boost is not included in RHEL3, that's the only way to make sure we are
looking at exactly the same source.
Anyway, I guess this is a dup of #164421, though need the preprocessed source

I have verified this is a dup of #164421, pasting here the fix as well.
