[Freemint-list] shel_write() causing memory violation?

Guys,
apart from writing essays on pretty displays I do some programming, too. ;)
I'm trying to fix the last remaining bug (I know of) in TosWin2 and that is
a memory violation if TW2 is not started and a TTP/TOS is executed via
$TOSRUN.
It all boils down to this:
::::::::::::::
tmp1.c
::::::::::::::
#include <gem.h>
#include <stdio.h>
int main() {
short id = shel_write(1, 1, 1, "c:\\tmp2.app", "");
printf("ID: %d\n", id);
return 0;
}
::::::::::::::
tmp2.c
::::::::::::::
#include <gem.h>
#include <osbind.h>
int main() {
short id = appl_init();
short Wchar, Hchar, Wbox, Hbox;
short phys_handle = graf_handle (&Wchar, &Hchar, &Wbox, &Hbox);
short handle = phys_handle;
short work_out[57];
short work_in[11] = {Getrez() + 2,1,1,1,1,1,1,1,1,1,2};
v_opnvwk (work_in, &handle, work_out);
v_clsvwk (handle);
appl_exit();
return 0;
}
If I run tmp2.app, everything is fine. But if I run tmp1.app (which
executes tmp2.app via shel_write()), I get a memory violation on the line
with v_opnvwk().
Do you have any idea why? Is it forbidden for some reason?
