107	crash in threads with cerr-usage when cin is a pipe	anonymous	bird	"Hi,

when I run the following program compiled with gcc 3.3.5 CSD1 and a input redirection I get SYS1808 with code 0005.

{{{
#include <iostream>
using namespace std;

void threadfunc(void*)
{  cerr << ""in thread\n"";
}

int main()
{  cerr << ""before beginthread\n"";
   _beginthread(threadfunc, NULL, 65536, NULL);
   cerr << ""after beginthread\n"";
   return 0;
}
}}}

{{{
D:\TEMP>gcc test.cpp -lstdc++

D:\TEMP>type test.cpp | test.exe
before beginthread
aifnt etrh rbeeagdi
ntSYS1808:
Der Prozeß wurde gestoppt. Der Softwarediagnosecode
(Fehlercode der Ausnahmebedingung) ist 0005.
}}}

Of course, the output to cerr is not serialized, but this does not matter. I removed the mutex only for simplicity.

The signal is triggerd immediately after the end of threadfunc if and only if
 * test.exe is called with input redirection and
 * there is at least one output to cerr in the thread (cout works!).

With gcc 3.2.2 the above program works as expected even with pipe input.
