------- Comment #11 from hjl at lucon dot org 2007-09-11 13:43 ------- .eh_frame section in the new crtend.S only has 4 byte:
[ 7] .eh_frame X86_64_UNWIND 0000000000000000 000000b8 0000000000000004 0000000000000000 A 0 0 4 which is the zero terminator: bash-3.2$ readelf -wf crtend.o The section .eh_frame contains: 00000000 ZERO terminator bash-3.2$ Sun linker doesn't properly handle ZERO terminator in .eh_frame. It looks like a Sun linker bug to me. BTW, did your elfdump report vs. (after): Unwind Section: .eh_frame FDE: [0x00000000] length: 0x00 cieptr: 0x18 initloc: 0x00000000 addrrange: 0x0000 Auxiliary vals: CIE: [0x00000004] length: 0x18 cieid: 0 version: 1 augstring: `zR' codealign: 0x1 dataalign: -8 retaddr: 16 It doesn't look like .eh_frame in the new crtend.o at all. That may be a bug in your elfdump. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33100
