Forget this. I get the same results here.

However, if you add a "#error" at the right place in ceval.c, you'll see that computed gotos are enabled. It seems more of a sysconfig bug or limitation. In pyconfig.h, I have the following:

$ \grep GOTO pyconfig.h
#define HAVE_COMPUTED_GOTOS 1
/* #undef USE_COMPUTED_GOTOS */

Which apparently sysconfig translates as USE_COMPUTED_GOTOS being equal to 0, which I think is wrong.
