Summary: Solaris Forte 7 &8 bug in test_long
Initial Comment:
Python 2.2.3
This is for information. It is a bug in Sun's Forte 7
and 8 compiler suite, very unlikely to affect most
people, and I am pursuing it at low priority with Sun.
I am reporting it as it will cause the tests to fail
if anyone switches floating-point trapping on.
In PyFloat_FromString in floatobject.c, there is a
call to strtod. In test_long, this is supplied with
a huge argument. Sun have misunderstood C99 (puke)
to state that the wording in Annex F requires strtod
to raise an exception if it overflows, and have again
misunderstood C99 to mean that implies SIGFPE if
trapping is on. I don't blame them for getting
confused, but their interpretation is wrong - or, at
least that what was stated when C99 was in draft!
Generically, we can expect to see more vendors get
confused by C99, and especially by the horrible
floating-point changes.
Yuck.
