When compiled with gcc 3.2.1 and the supplied libstdc++, it is 1, indicating that the inserter fails to set badbit when an exception occurs during output. Regards Martin >How-To-Repeat: #include <ostream> #include <streambuf> struct buf: std::streambuf { virtual int_type overflow (int_type) { throw 0; return -1; } }; int main () { buf b; std::ostream strm (&b); strm.exceptions (std::ios::badbit); try { strm << 0; } catch (int) { return !(strm.bad ()); } catch (...) { return 2; } return 3; } >Fix: >Release-Note: >Audit-Trail: >Unformatted:
