Re: [BUG] xemacs-21.4.* Digital UNIX and regex.c with REGEX_MALLOC

I'm not sure if you can raise the stack size once your
program has started. I know that you can do it for threads
on digital unix very simply. We could put code like this
where appropriate.
static int __check_stack_requirements(int necessary)
{
#ifdef RLIMIT_STACK
struct rlimit rl;
if (getrlimit(RLIMIT_STACK,&rl) == 0)
{
if (rl.rlim_cur >= necessary)
/* Everything will work just fine... */
return (0);
}
if (rl.rlim_max < necessary)
{
/* Maximum stack size is still too small...
** Should we just fail to start?
*/
return (-1);
}
How can you know how much is necessary? In my case the stack overflow
occurred when opening BibTeX-file with long abstract fields. It's
not possible to know beforehand how long abstracts there might be.
And please no failing, I'd prefer just a warning like with REGEXP_MALLOC:
itimer "itimer-<1>" signaled: (error "Stack overflow in regexp
matcher")
