:While looking for the memleak I found that the following leads to

:Should one consider this as a perl bug?

Absolutely. This bug was introduced between 5.005_02 and 5.005_03; in the
current development track, it was fixed between _61 and _62. It also
appears in 5.004_05 (but not 5.004), so I would guess that it appeared
also between 5.004_04 and 5.004_05.

I don't know what 5.005_62 patch might have fixed it; perhaps this one:
