Consider the attached code ice.c . When compiled, it is giving an internal
compiler error. I was not able to reduce it any further. Would appreciate if
someone can reduce it further.

Initially, I asked this question on gcc-help
http://gcc.gnu.org/ml/gcc-help/2009-01/msg00109.html . I narrowed down the
problem further and reporting it here.

So if I am reading this thread correctly this is really a bug in Solaris's
yacc?

My initial guess was that it is a bug in yacc. But now I do not think so. I
have compiled bison (which supersedes yacc). I still see this bug with bison
(and no yacc).

I can't believe I am so dense... I installed bison, removed /usr/ccs/bin from
the PATH. But I forgot to recompile gcc with the new update. I was still trying
to bootstrap from the old compiler. Let me recompile gcc (with bison) and see
if the problem goes away. It usually takes one day to finish...

I would like to confirm that, even after recompiling gcc with bison, I am still
getting the internal compiler error. There is no yacc, no /usr/ccs/bin in $PATH
when gcc was compiled.

If someone is working on this, you might want to look at #37798, too. I have no
idea wether these two are connected, but GCC definitively has problems with
alignment on SPARC.

Btw, the default extension for preprocessed sources is .i, just pass

to the compiler to get the file.

------- Comment #14 from ebotcazou at gcc dot gnu dot org 2009-02-08 10:26 -------
This is a bug in the qsort implementation on Solaris 8:
Breakpoint 1, sort_coalesce_list (cl=0x1ce4b80)
at /nile.build/botcazou/gcc-head/src/gcc/tree-ssa-coalesce.c:434

(gdb) p cl->sorted

(gdb) p num
$23 = 8
(gdb) continue
Continuing.
Program received signal SIGSEGV, Segmentation fault.
0x00f1bb00 in compare_pairs (p1=0x1cc4e84, p2=0x1cc4e8c)
at /nile.build/botcazou/gcc-head/src/gcc/tree-ssa-coalesce.c:318
318 result = (* pp2)->cost - (* pp1)->cost;
i.e. the comparator is invoked on &cl->sorted[-1], which is invalid.

------- Comment #15 from ebotcazou at gcc dot gnu dot org 2009-02-08 10:58 -------
> This is a bug in the qsort implementation on Solaris 8:
Browsing the Sun database shows several related tickets, but most have been
closed as "not a defect" on the ground that the comparator function fails to
impose a total order on the array. That's the case here because of overflow:
(gdb) p cl->sorted[0].cost
$29 = 2147483646
(gdb) p cl->sorted[1].cost
