As you may already have guessed, it does *not* print

But does it print "TerminateProcess succeeded" and exit with

TerminateProcess() terminates the CURRENT process when it is
passed INVALID_HANDLE_VALUE. Aaaaargh!
How did INVALID_HANDLE_VALUE get so far in the code as to reach
TerminateProcess? Shouldn't an enforce call have been in place to
validate whatever the source of the handle is?
Anyway, this is documented behavior. You can pass
GetCurrentProcess() to TerminateProcess to terminate the current
process.
Your plight was caused by the unfortunate (or perhaps,
unforesighted) coincidence that GetCurrentProcess() returns the
special (magic) value of (HANDLE)-1, the same value of
INVALID_HANDLE_VALUE.
