I'm not 100% sure, but I think the reinit of the Tcl library
was more important than the 100% clean Finalize, but both were
considered. I need to make sure that the resetting of init to
0 isn't correct for cases like the browser plugin, where Tcl
is constantly fully unloaded and reloaded.
OK. I have written a small progam:
#include <stdio.h>
#include <tcl.h>
int main (int argc, char **argv)
{
char cmd[128];
Tcl_Interp *interp;
/* First try */
Tcl_FindExecutable(argv[0]);
interp = Tcl_CreateInterp();
sprintf(cmd, "set a 1111");
Tcl_Eval(interp, cmd);
fprintf(stderr, "%s: %s\n", Tcl_GetNameOfExecutable(),
Tcl_GetStringResult(interp));
Tcl_DeleteInterp(interp);
Tcl_Finalize();
/* Second try */
Tcl_FindExecutable(argv[0]);
interp = Tcl_CreateInterp();
sprintf(cmd, "set a 2222");
Tcl_Eval(interp, cmd);
fprintf(stderr, "%s: %s\n", Tcl_GetNameOfExecutable(),
Tcl_GetStringResult(interp));
Tcl_DeleteInterp(interp);
Tcl_Exit(0);
}
Compile it and run:
zvpb:~/tmp zoran$ gcc -g -o t a.c -I/usr/local/include -L/usr/local/lib
-ltcl8.4g
zvpb:~/tmp zoran$ gdb ./t

I think this is correct now. What's still left is to check the Windows
port. I do not have Windows at hand unfortunately, but I changed that
part as well. If you can checkout the core-8-4-branch on Windows and
try it out...
The leak is gone, as I already reported.
