Hello Caz,
the problem is in constant in string 1781 in file dwarf2read.c:
******
1778: pdi = pdi->die_sibling;
1779:
1780: if (debugkernel) {
1781: if (pdi != NULL && pdi->highpc >= *0xffffffffff000000*) {
1782: if (pdi->die_sibling != NULL)
1783: pdi = pdi->die_sibling;
1784: }
1785: }
******
I think code in strings 1780-1785 is useless because of 1778 and it can be
safely removed.
Regards,
Dmitry.
