I really don't know against which component to file this... DESCRIPTION: I was working with the refcount balancer last weekend, and I was trying to figure out why an nsAppShell was leaking (since that seems like it could hold on to other things). It *seemed to me* that the nsAppShell was held on to by an nsAppShellService, which was held on to by an XPCWrappedNative. This XPCWrappedNative seemed to be leaking because it wasn't being garbage collected by the JS GC. (Looking at one that didn't leak showed the garbage collection.) I'm not 100% sure of this analysis, but it's worth looking into. (In particular, it could be a different XPCWrappedNative than the one I'm looking at that's leaking the appshell, and it *could* be leaking in a different way.) STEPS TO REPRODUCE: * start mozilla with XPCOM_MEM_LEAK_LOG setenv'd to 1 * click "Exit" when you see the profile manager ACTUAL RESULTS: * the following objects leak: 1 nsAppShellService 1 nsAppShell 13 nsXPCWrappedNative EXPECTED RESULTS: * no leaks :-) DOES NOT WORK CORRECTLY ON: * my mozilla build from last weekend ADDITIONAL INFORMATION: Some refcount balancer output available **when my PC is on**: an XPCWrappedNative that was not leaked: http://dbaron.student.harvard.edu/u/david/leaks/nsXPCWrappedNative.balance-good5.txt an XPCWrappedNative that was leaked (with ignore-balanced-subtrees): http://dbaron.student.harvard.edu/u/david/leaks/nsXPCWrappedNative.balance-ib1.txt an XPCWrappedNative that was leaked (without ignore-balanced-subtrees): http://dbaron.student.harvard.edu/u/david/leaks/nsXPCWrappedNative.balance1.txt The nsAppShellService that was leaked: http://dbaron.student.harvard.edu/u/david/leaks/nsAppShellService.balance-ib.txt (and there are other files in the same directory if you want to poke around)
