New subject: Boost format library Segmentation fault with Intel 8.1

22 Nov 2004

      Hi!

I get a segmentation fault with Intel compiler 8.1 using the fallowing code

#include 
#include <iostream>

int main() {
   std::cout << boost::format("writing %1%,  x=%2% : %3%-th try") % "toto" % 
40.23 % 50 << std::endl;
   return 0;
}

#9  0x4102e7f8

The same code works perfectly with gcc-3.4.2 under linux. Is this a bug in 
boost format library or a Intel compiler problem?

My system: Debian, boost-1.31.0, gcc-3.4.2, Intel compiler 8.1
