Hello,

i posted a problem against boost::serialization.
(http://article.gmane.org/gmane.comp.lib.boost.user/54935).
But now i could track it down to boost::spirit.
I have extracted boost::serialization stuff , which is dealing with boost spirit, in a mini demo program
(see attached tar file).

It accepts XML input if compiled with -O0 or -O1 and returns:

|hpux03 407> make sample
        /usr/local/gcc-3.4.4/bin/g++ -g -mlp64 -Wall -mtune=itanium2 -O1 -I/nfs/uh01/frank/userspace/OPSC_DIAXHBS_dev_R2.2_hpport/include -c sample.cc 
        /usr/local/gcc-3.4.4/bin/g++ -g -mlp64 -Wall -mtune=itanium2 -O1 -I/nfs/uh01/frank/userspace/OPSC_DIAXHBS_dev_R2.2_hpport/include -c fbe_basic_xml_grammar.cc 
./sample
        /usr/local/gcc-3.4.4/bin/g++ -g -mlp64 -Wall -mtune=itanium2 -O1 -I/nfs/uh01/frank/userspace/OPSC_DIAXHBS_dev_R2.2_hpport/include -lunwind -o sample sample.o fbe_basic_xml_grammar.o 
|hpux03 408> ./sample
test is '<pDeleteHlrSubscriberIn class_id="0" tracking_level="0" version="0">'
parse_start_tag('<pDeleteHlrSubscriberIn class_id="0" tracking_level="0" version="0">') returned 1

But it fails, if i use -O2 or -O3:

|hpux03 411> make sample
        /usr/local/gcc-3.4.4/bin/g++ -g -mlp64 -Wall -mtune=itanium2 -O2 -I/nfs/uh01/frank/userspace/OPSC_DIAXHBS_dev_R2.2_hpport/include -c sample.cc 
./sample
        /usr/local/gcc-3.4.4/bin/g++ -g -mlp64 -Wall -mtune=itanium2 -O2 -I/nfs/uh01/frank/userspace/OPSC_DIAXHBS_dev_R2.2_hpport/include -c fbe_basic_xml_grammar.cc 
        /usr/local/gcc-3.4.4/bin/g++ -g -mlp64 -Wall -mtune=itanium2 -O2 -I/nfs/uh01/frank/userspace/OPSC_DIAXHBS_dev_R2.2_hpport/include -lunwind -o sample sample.o fbe_basic_xml_grammar.o 
|hpux03 412> ./sample
test is '<pDeleteHlrSubscriberIn class_id="0" tracking_level="0" version="0">'
parse_start_tag('<pDeleteHlrSubscriberIn class_id="0" tracking_level="0" version="0">') returned 0

Is it a bug of gcc-3.4.4? (for HP-UX B11.31 ia64?)
Or boost::spirit using experimental C++ feature (for level of gcc-3.4.4)?

- many thanks!

Frank Bergemann
