lembark has asked for the wisdom of the Perl Monks concerning the following question:

Q: Has anyone seen this before? Say I generate a linked list with elements like: @$node = [ [], @data ]; $node = $node->[0]; this works. If I bless the last item in the list and undef the first one I see a message from DESTROY telling me that the list has been fully removed from memory. Catch: somewhere in the range of 32_000 .. 35_000 I'll get a segfault. This doesn't seem to be due to any memory leak since I can run the thing for days counting from 1 .. 32_000 and back down again without any increase in the memory footprint (after the first pass up to 32K). This happens in 5.8.8 & 5.10.0 (on linux, w/ gcc-4.1.2). Havn't found any mention of this anywhere else. I can post the code to reproduce the problem if anyone really cares.
