I see.

I believe it is not.
The error I've reported is thrown by AWK called from deep abbys of
pkgsrc. AWK sits on the execution stack high above any hardware (even
emulated), so I can't really think of debugging emulator
without exact command AWK was executed, at least.

Is it possible to trace pkgsrc and find where AWK is called from
and find exact AWK command executed?

I have forwarded the whole story to the QEMU team:

http://lists.nongnu.org/archive/html/qemu-devel/2011-01/msg01509.html

However, a reproducible test case is essential and I'm not surprised.
