I can reproduce it also on powerpc-apple-darwin6.6, there has been some talk about
getting this to work or having this be an error but I do not know what the final outcome
was.

------- Additional Comments From bernie at develer dot com 2003-09-27 03:52 -------
Also happens on mainline (20030927).
Backtracing with GDB, it seems that htab_clear_slot()
from libiberty fails its consinstency checks and
abort()s:
if (slot < htab->entries || slot >= htab->entries + htab->size
|| *slot == EMPTY_ENTRY || *slot == DELETED_ENTRY)
abort ();
It's invoked by other functions called by cgraph_remove_node().

------- Additional Comments From zlomek at gcc dot gnu dot org 2003-10-01 16:19 -------
This happens on x86-64 too.
The problem is that
when adding to hashtable in cgraph_node () DECL_ASSEMBLER_NAME is "__finite"
and when removing node in cgraph_remove_node () DECL_ASSEMBLER_NAME is
"__GI___finite".
Thus the hash key is different so it finds different slot in cgraph_remove_node ()
which is in this testcase EMPTY_SLOT.

I just got gcc from CVS (sources.redhat.com) and during compilation of glibc,
I getting error on line 30 of drand48_r.c, any workarounds? Any gcc build
options? Please advice.........

One work-around is to use -fno-unit-a-time with -O2 when compiling drand48_r.c.
