Package: libqtcore4-perl Version: 4.8.4-1 Severity: normal Hi there,
as I was learning to use Qt and the perl bindings, I found myself unable to cope with a slow but steady memory leak due to C++ objects (constructed from within perl) never being destroyed (neither when the variable goes out of scope nor when explicitly calling ->DESTROY). Steps to reproduce: - Execute the attached minimal test case. (Basically a timer to call Qt::Color() 10000 times per second) - Using "top" and shift-M, watch as the test case's resident size steadily grows at roughly 1 MB/s (=100 bytes/call) and finally rises above iceweasel. I positively tested Qt::Color, Qt::Point, Qt::Pen, etc. as well as Qt::Object. Calling Qt::Object's deleteLater() did not help either. Qt::Ushort and Qt::String were not affected (I guess, they're not backed by C++ objects?). I also tried to avoid creating new objects in timer events, which reduced the problem but did not eliminate all memory leaks so far. I tried getting my hands on the source of 4.8.4-1+b1 to check if the problem has been fixed there, but apt refused to cooperate.
