First, are you shure this is running under the snapshot?  what does
`uname -a' print when called right before the below gdb call?

Not really.  We can't quite trust the information returned for frames

weird since no Cygwin application would call a vsprintf functions
from ntdll.dll, if it's linked correctly.
