Subject [jira] Commented: (STDCXX-140) [NetBSD 3.0] accum hangs during execution
Date Tue, 07 Feb 2006 17:59:05 GMT
    [ http://issues.apache.org/jira/browse/STDCXX-140?page=comments#action_12365455 ] 

Martin Sebor commented on STDCXX-140:
-------------------------------------

I have seen a similar issue on Cygwin. Here are my notes

The library builds just fine now (at least 11s does), but I ran into
a runtime issue that I haven't had time to analyze yet. A simple
integer insertion followed by std::endl hangs:

   #include <iostream>
   int main () { std::cout << 0 << std::endl; }

I can't even stop the debugger by pressing Ctrl+C so it's kind of
tricky to figure out what's going on. It seems to hang on return
from ctype::widen() somewhere in cygwin.dll. (This is with gcc
3.3.3 and gdb 6.3.50_2004-12-28-cvs on CYGWIN_NT-5.0 RW1266
1.5.12(0.116/4/2)).
