Hi Andrew,
attached is my little test program I use.
The error is seen both on x86 and PowerPC:
* i686 i686 i386 GNU/Linux
* ppc64 ppc64 ppc64 GNU/Linux
following versions of binutils:
x86: binutils-2.17.50.0.6-5.el5
PowerPC: binutils-2.17.50.0.12-4
objdump -W says:
objdump: Error: Location lists in .debug_info section aren't in ascending
order!
Contents of the .debug_loc section:
Offset Begin End Expression
00000000 080485b4 080485b5 (DW_OP_breg4: 4)
00000000 080485b5 080485b7 (DW_OP_breg4: 8)
00000000 080485b7 0804868b (DW_OP_breg5: 8)
00000000 <End of list>
objdump: Warning: There is an overlap [0x2c - 0xfffffffe] in .debug_loc
section.
objdump: Warning: Offset 0xfffffffe is bigger than .debug_loc section size.
objdump: Warning: There is a hole [0xfffffffe - 0x2c] in .debug_loc section.
As seen in comment #1 readelf also gives that error. AFAIK readelf does not
use BFD library as GDB and objdump do so I believe this is not an error
in BFD library.
I use GDB's current head. I also tried gdb-6.5-25.el5_1.1 and it also occurs.
Regards,
Markus Deuling
