System: FreeBSD p3.my.net 4.4-STABLE FreeBSD 4.4-STABLE #0: Wed Nov 21 20:26:00 MSK 2001 root@p3.my.net:/usr/src/sys/compile/KERNEL i386
>Description:
I have got "out of swap space" errors, when using function 'dialog_gauge'
from libdialog.
>How-To-Repeat:
Try to call function 'dialog_gauge' about 100000 times, and you'll
see how your swap size is growing. I'm using libdialog from
4.4 STABLE (got from CVS).
>Fix:
The only change required is to insert releasing window memory function
(delwin(gw)) just before last line, containing 'return', of function
'dialog_gauge'.
Here is also the patch
