When qemu is run under valgrind, valgrind shows the following output
on exit:

==3648== 1 errors in context 2 of 2:
==3648== Syscall param timer_create(evp) points to uninitialised byte(s)
==3648==    at 0x54E936A: timer_create (in /lib/librt-2.9.so)

This patch is a simple fix to remove this potential problem.

This fixes a SIGSEGV error on qemu exit.

Here is the valgrind output related to this error

==3648== Process terminating with default action of signal 11 (SIGSEGV)

This simple fix check for a valid pointer as host_alarm_handler is
also called after alarm_timer is released in the exit path.

This text is no longer accurate. After the patch is applied, the

This patch is also a candidate for the stable branch. (The URL above is
probably generated from the stable branch anyways, so maybe it goes

ARMv7 defines a new behavior for ARM data processing instructions
compared to earlier architecture revisions; when the destination
