| Description: |
Windows only:
If Tcl_OpenTcpServer() is the very first Socket call, then the thread data is not set correctly resulting in a crash. Found in an embedded application. Not reproducible via tclsh.
tclWinSock.c:
2064 ThreadSpecificData *tsdPtr = TclThreadDataKeyGet(&dataKey);
2065
2066 if (TclpHasSockets(interp) != TCL_OK) {
2067 return NULL;
2068 }
The order above, KeyGet followed by HasSocket, is backwards.
that's a week of my life I'll never get back :)
