[Qemu-devel] RE: [Bug 702885] Re: "Internal resource leak" error with ARM NEONvmull.s32 insn

[Wolfgang Schildbach]

Duh. I had missed the greater part of Christophe's patch (I am still
having trouble with my mail client; applying patches off the list is
manual for me).

With both patches applied, indeed the bug filed on launchpad seems
fixed. On my second test case, behaviour is much improved. Thanks much!
