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().
