Hi,

void XS_Win32__GUI__Combobox_GetLBText(interpreter*, cv*)(
PerlInterpreter * my_perl = &(indirect),
CV * cv = &(indirect)
)
This one is a little harder to reproduce, but I think it's easy enough to
solve:
[from line 399 in Combobox.xs]
cbString = SendMessage(handle, CB_GETLBTEXTLEN, index, 0);
if(cbString != LB_ERR) {
szString = (char *) safemalloc(cbString);
It looks like we're not allocating enough space for the string - adding 1 to
cbString stops the crash (another issue is that we're assuming 1 byte = 1
char which might not be the case...).
Cheers,
jez.
