Hi, some supplementary information: The problem happens also for gcc-3.4.6 - which is the final version of gcc-3.x.x series. If i compile for 32 bit there is even a coredump for execution: (gdb) r Starting program: /nfs/uh01/frank/TESTX/sample test is '<pDeleteHlrSubscriberIn class_id="0" tracking_level="0" version="0">' Program received signal SIGBUS, Bus error si_code: 1 - BUS_ADRALN - Invalid address alignment. Please refer to the following link that helps in handling unaligned data: http://docs.hp.com/en/7730/newhelp0610/pragmas.htm#pragma-pack-ex3. boost::spirit::grammarboost::spirit::nil_t

::grammar (this=0x40025cf0) at sp_counted_base_gcc_ia64.hpp:38 38 "r"(pw));

I opened a bug for gcc: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42791 And i asked HP for confirmation. I'll keep you informed... best regards, Frank ___________________________________________________________ Preisknaller: WEB.DE DSL Flatrate für nur 16,99 Euro/mtl.! http://produkte.web.de/go/02/
