Re: [Fink-users] gfortran from gcc43-4.3.3-100 throwing "Illegal instruction" errors on 10.5.6 G4

[Alexander H. <ale...@gm...>]

The gcc43 build fails because of an illegal instruction in the gfortan
portion of the build:

from my
/sw/src/fink.build/gcc43-4.3.3-1000/darwin_objdir/powerpc-apple-darwin9/libgfortran/config.log:

I guess I can pin the date that gfortran last worked for me on this box
as November 11 of last year, because I've got an octave .deb file from
that date. Possibly later.  And it's _only_ gfortran that seems
afflicted by this:  clamav, which uses the C compiler from gcc43, builds
happily. 

What's really odd to me is that I get the same error when building
anything using the gfortran from gcc43-4.3.1-1000, which did
successfully build on my system (in June last year).   So presumably
_that_ worked at one point and some later change now causes the runtime
breakage.

Anyway, I'll put the build log and build directory online at some point
soon.
