problem with iostream

[martin.berger@talk21.com]

hello, i have just upgraded to the latest version of redhat linux
and suddenly my g++ compiled programs fall over. the problem seems to
be related to the iostream library. here is an example program that
fails (the details of how cout is used dont seem to matter. the fault
seems to occur every time cout is used).

#include <iostream>

int main( int, char* )
{
      cout << "" << endl;
}

(below you'll find the relevant compiler and gdb output). alas, i'm not too
familiar with the g++ system and the redhat distribution. i suspect
that the problem is some trivial omission in my setup. but i can't work out
what. can you please help?

thanks, martin
