Re: [Chicken-hackers] 4.7.5 modified -> 4.8.2: heap full while resizing is back

[Jörg F . Wittenberger]

Thanks Mario for your remark.

However, the bug will not effect me.

Let's say I don't remember whom I eventually sent my initial
implementation as offered here
http://lists.nongnu.org/archive/html/chicken-hackers/2012-05/msg00008.html

The code I'm using since doesn't have that problem.
Dunno how it came in.

Thanks anyway.
