Gdb is still the same. Works but partially and on some apps.

iOS Terminal worked on my ARMv7 device ^^

I'm on 8.4 and since some update about 2 months ago ( either in Cydia, gnu debugger or possibly a supporting library ) GDB only returns debugging information in relation to the _mh_execute_header ().

0x001f000c in _mh_execute_header ()
4: $r2 = 2041261
3: $r1 = 1
2: $r0 = 19582444
1: x/i $pc 0x1f000c: 78 44 00 68 stmdavs r0, {r3, r4, r5, r6, r10, lr}

performing a disassemble command at this break returns hundreds of thousands of lines of bad commands:

<snip>

0x000a3b50 <_mh_execute_header+248656>: 02 98 00 f1 undefined instruction 0xf1009802
</snip>

Any idea on what I can do to revert and have it work the way it was 2 months ago?
