vector/algorithm breaks iostream?

["Edwards, Phil" <pedwards@ball.com>]

EGCS 19990502, v3 checked out today, i586-pc-linux-gnu.

Including <iostream> works fine, but if <vector> or <algorithm> are
previously included, then output operations to standard {output,error} are
never seen.  This is not to imply that vector and algorithm are the only
headers that cause this problem; it just happens that those are the two I
was working with at the time.

Later tonight I'll try to step through in gdb.


The source of a simple testcase is:

#ifdef BREAKME
#  if (BREAKME == 1)
#    include <vector>
#  elif (BREAKME == 2)
#    include <algorithm>
#  endif
#endif

#include <iostream>

int main ()
{
    std::cerr << "Some text!";
    std::cerr << std::endl;
}


The output of the three combinations is:

    [skylab 156]> g++ -I$HOME/3/include/g++-v3 -L$HOME/3/lib
                  -DBREAKME=1 simple.cc
    [skylab 157]> ./a.out
    [skylab 158]> g++ -I$HOME/3/include/g++-v3 -L$HOME/3/lib
                  -DBREAKME=2 simple.cc
    [skylab 159]> ./a.out
    [skylab 160]> g++ -I$HOME/3/include/g++-v3 -L$HOME/3/lib
                  simple.cc
    [skylab 161]> ./a.out
    Some text!
    [skylab 162]> 


The output of "g++ -v --save-temps -Iallthatstuff -Lallthatstuff -DBREAKME=1
simple.cc" is here, and simple.ii.gz (44Kb after gzip -9) is attached.
