Py_IS_INFINITY is defined as
#ifndef Py_IS_INFINITY
# if defined HAVE_DECL_ISINF && HAVE_DECL_ISINF == 1
# define Py_IS_INFINITY(X) isinf(X)
# else
# define Py_IS_INFINITY(X) ((X) && \
(Py_FORCE_DOUBLE(X)*0.5 == Py_FORCE_DOUBLE(X)))
# endif
#endif
The test still fails when built --with-pydebug.
(gdb) b isinf
Function "isinf" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (isinf) pending.

isinf is #defined in math.h to
#define isinf(x) \
((sizeof (x) == sizeof (float)) ? \
__isinff(x) \
: (sizeof (x) == sizeof (double)) ? \
__isinf(x) \
: __isinfl(x))
but setting a bkp on it changes nothing.

Setting a bkp on PyLong_FromDouble() shows that it's not called.
Sorry, this doesnt make sense to me...
