hi all, i received this bug report for the Boost debian package version 1.31.0-4, the full log is available at [0]. it is reproducible on ia64 architecture. anybody with in depth knowledge of the format library is able to give me a hint about where the problem might be? i cannot provide any access to the debian project's ia64 box but i'm available to perform any test i'm asked to further delve into the bug. best regards domenico [0] http://bugs.debian.org/247643 ----- Forwarded message from Martin Pool <mbp@samba.org> ----- Date: Thu, 06 May 2004 17:03:38 +1000 From: Martin Pool <mbp@samba.org> To: submit@bugs.debian.org Reply-To: Martin Pool <mbp@samba.org>, 247643@bugs.debian.org Cc: mbp@sourcefrog.net Subject: Bug#247643: boost::format completely broken on ia64 Package: libboost-dev Version: 1.31.0-4 Severity: important X-Debbugs-CC: debian-ia64@lists.debian.org Here is a test case, extracted from the examples in http://www.boost.org/libs/format/example/sample_formats.cpp: --------------- #include <iostream> #include <boost/format.hpp> using namespace boost; using namespace std; int main(void) { cout << format("Hello %d!\n") % 69; return 0; } ----------------- I build this with g++ -o boost-format-bug boost-format-bug.cpp On i386 it works fine. On ia64, with g++ 4:3.3.3-2 and libstdc++ 1:3.3.3-6, it crashes. In fact I cannot find any use of the format class other than passing a constant string which does not crash. gdb shows Catchpoint 1 (exception thrown) 0x2000000000149981 in __cxa_throw () from /usr/lib/libstdc++.so.5 (gdb) bt #0 0x2000000000149981 in __cxa_throw () from /usr/lib/libstdc++.so.5 #1 0x20000000000acc50 in std::__throw_length_error () from /usr/lib/libstdc++.so.5 #2 0x200000000012fc30 in std::string::_M_replace_safe<char const*> () from /usr/lib/libstdc++.so.5 #3 0x200000000012ba40 in std::string::append () from /usr/lib/libstdc++.so.5 #4 0x400000000000db60 in boost::io::detail::(anonymous namespace)::mk_str<char, std::char_traits<char> > () #5 0x400000000000c900 in boost::io::detail::(anonymous namespace)::put<char, std::char_traits<char>, int const&> () #6 0x400000000000ac60 in boost::io::detail::distribute<char, std::char_traits<char>, int const&> () #7 0x40000000000076c0 in boost::io::detail::feed<char, std::char_traits<char>, int const&> () #8 0x4000000000003fe0 in boost::basic_format<char, std::char_traits<char> >::operator%<int> () #9 0x4000000000003d00 in main () Regards Martin ----- End forwarded message ----- -----[ Domenico Andreoli, aka cavok --[ http://people.debian.org/~cavok/gpgkey.asc ---[ 3A0F 2F80 F79C 678A 8936 4FEE 0677 9033 A20E BC50
