Hi,
You're right. My mistake.
Best.

In that case the loop will be:
while (capture != NULL)
capture = capture->next_one;
It is not necessarily an infinite loop.

Hi,
With fix in th SVN, the following may occur;
next is NULL.
If the first capture->type != IMASK_CAPT_OPEN, an infinite loop will occur.
Maybe switch to Do While loop?
Best.
Ranier.

Fixed and committed to SVN. I have no idea if that condition could occur...

Hi,
Issue found by Coverity Scan.
CID 210623 (#1 of 1): Explicit null dereferenced (FORWARD_NULL)
9. var_deref_op: Dereferencing null pointer next.
File: iup_maskmatch.c
Function: iMaskMatchCaptureResult
code:
next = NULL;
while (capture != NULL)
{
if (capture->type == IMASK_CAPT_OPEN)
{
ImaskCapt *cap = capture->next_one;
capture->next_one = next;
next = capture;
capture = cap;
}
else
{
if (capture->pos >= next->pos)
(*vars->function)((char)capture->which_one, next->pos, capture->pos,
vars->text, vars->user);
next = next->next_one;
capture = capture->next_one;
}
}
Need rethink this function, if capture->type != IMASK_CAPT_OPEN and
next is NULL,
Best.
Ranier.
