[Bug c/23541] New: all error messages produce segfault ICE

[fgccbz0 at greynode dot net]

when compiled not just to target sparc64 but also to be hosted on sparc64
instead of just sparc, the resulting compiler segfaults most of the time when it
tries to print error messages. For instance, when compiling a file containing
just a bogus preprocessor directive, like so:

#asdfadfa

The problem seems to be that gcc-4.0.1/intl/dcgettext.c:53 can't see a
declaration of libintl_dcgettext, and so the result of the call is cast to an
int, losing its high word, before being returned.  I think
gcc-4.0.1/intl/gettextP.h:213 has caused libgnuintl.h to provide only macros
instead of declarations. Perhaps in libgnuintl.h the various extern libintl_FOO
declarations should be outside of the #ifdef _INTL_REDIRECT_INLINE conditionals,
so that even when using _INTL_REDIRECT_MACROS and not INTL_REDIRECT_INLINE, the
declarations of the libintl_FOO are published to the includer.

Using a handy 32-bit hosted gcc-4.0.1 I had already built, I built using
./configure --enable-languages=c,c++ --with-gnu-as --with-as=BLAH/bin/as
--with-gnu-ld --with-ld=BLAH/bin/ld sparc64-sun-solaris2.9

This sounds like a bug in your configuration as nobody else I know of has had this problem.

Are you sure these unnamed other people are using not just 64-bit targeted but
64-bit hosted builds?

What exactly kind of bug in my configuration do you mean? I've pointed you at
exactly what's going wrong - do you mean that I shouldn't wind up in this case
where I don't pick up the declarations of the libintl_* functions?

4.1.0 works just fine:
http://gcc.gnu.org/ml/gcc-testresults/2005-08/msg00241.html
So does 4.0.2:
http://gcc.gnu.org/ml/gcc-testresults/2005-08/msg00182.html

So it has to be your configuration is different from Eric's.

Oh and there is nothing criticial about this bug as it is not reproducible on other's machines.

Thanks.

Evidently. The question is how. Is there anywhere I could get log of the build
from such a working version?

> Oh and there is nothing criticial about this bug as it is not reproducible on

(Did I re-flip that? Sorry - that was unintentional).

I'm not really sure how to proceed here. I've told you a symptom, a diagnosis
describing a probable flaw in the code, and possible solution. You've pointed me
at some logs from a person I don't know with an invalid e-mail address which
demonstrate that a differently configured build I can't access of a different
version of the software in a unspecified environment passed some tests.

May I ask how you'd proceed in my situation? I'm perfectly open to the
possibility that the problem's on my end, but I don't know how I'd find it. Your
criterion for taking me seriously seems to be that my configuration match that
of an inaccessible third party.

Eric Botcazou is sparc maintainer:
sparc port              Eric Botcazou           ebotcazou@libertysurf.fr


It sounds like you have a mismatching header installed and nothing more.

Such a difference is certainly possible - thank's for the e-mail address. That
ought to provide the hook I need to continue.

Could you post the exact configure line and command line you used to build the
compiler?  And the output of 'gcc -v' for the bootstrap compiler?
