Title:
  "Internal resource leak" error with ARM NEON vmull.s32 insn

Status in QEMU:
  New

Bug description:
  This bug occurs in qemu, commit
  78a59470e6bbc6e16dc4033767492649c1ae4cfd (most recent as of
  01/14/2011).

  Compile, assemble, and link the code below, with the ARM tools. (I use
  ARM C/C++ Compiler, 4.1 [Build 462]).

  armasm --cpu Cortex-A8 --licensing=3Dflex foo.s
  armcc --cpu Cortex-A8 --licensing=3Dflex -o main -L--sysv main.c foo.o

  Execute on qemu-arm and observe an "Internal resource leak" message.

  > qemu-arm main
  Internal resource leak before 0000818c

  int main(void)
  {
    void foofunc(void);
    foofunc();
