Hi,
the following snippet of code leaks memory:

busybox ash -c 'f() { while :; do local a=1; done } ; f'

Hello,

I've encountered this problem in one of my script, causing the system to be out of memory after several weeks. As a workaround I've moved the declaration of the local variable outside of the while loop.

Any chance to get a real fix?

Happens with 1.22.1 (at least), but seems to be already fixed in current git.
