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

Subject: Bug#247643: boost::format completely broken on ia64

Package: libboost-dev
Version: 1.31.0-4
Severity: important
X-Debbugs-CC: debian-ia64_at_[hidden]

Here is a test case, extracted from the examples in

#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
