This bug report originated from Nokia internal issue QT-674
--- Description ---
in Collector.cpp, vm_map returns NULL address.
The fix for https://bugs.webkit.org/show_bug.cgi?id=34888 should also help with this. _But_ you still need to explicitly target Leopard; it's currently not possible to build a binary that's going to work on both Tiger and Leopard. I think we would need a Qt-specific patch if we want to support that (i.e. disable the VM-tagging altogether somehow, or fall back to lowest common denominator allocation scheme).
