Hi!

During compilation of Python-1.5.2b2, the abovementioned pgcc
stopped with this message:

gcc  -march=3Dk6 -O6 -pipe -I./../Include -I.. -DHAVE_CONFIG_H -c ./selectm=
odule.c

        (nil)))
toplev.c:1461: Internal compiler error in function fatal_insn
cpp: output pipe has been closed
make: *** [selectmodule.o] Error 1

The beginning of the function (I'm including line 108) looks
like this:

selectmodule.c:    96   list2set(list, set, fd2obj)
selectmodule.c:    97           PyObject *list;
selectmodule.c:    98           fd_set *set;
selectmodule.c:    99           pylist fd2obj[FD_SETSIZE + 3];
selectmodule.c:   100   {
selectmodule.c:   101           int i;
selectmodule.c:   102           int max =3D -1;
selectmodule.c:   103           int index =3D 0;
selectmodule.c:   104           int len =3D PyList_Size(list);
selectmodule.c:   105           PyObject* o =3D NULL;
selectmodule.c:   106
selectmodule.c:   107           fd2obj[0].obj =3D (PyObject*)0;        /* s=
et list to zero size */
selectmodule.c:   108           FD_ZERO(set);
selectmodule.c:   109
selectmodule.c:   110           for (i =3D 0; i < len; i++)  {

I'm using the Linux-2.2.1 implementation of the FD_ZERO() macro.

The code of list2set() in file Modules/selectmodule.c is rather lengthy
(about three screen pages), so I'm not including it (it is publically
available anyway on the python homepage). The only unordinary thing
that I could see in the file were a few "goto"s to the end of the
function.

Changing the Makefile to use -O0 instead of -O6 made it compile.
-O1 did *not* work.

Please send me copies of replies, since I'm not subscribed. Thanks.

ciao,
johnny
