iOS debugger suggestion/ assistance

[miseaujeu]

I am using a TaiG jailbroken iPhone 5 with iOS 8.4.

When the default debugger, GDB, started returning gibberish sometime around November 2015 I got a different phone and have been patiently waiting for a 9.2+ jailbreak. Since there doesn't seem to be one coming I'm going back to the 8.4.

Does anyone know of a way to fix GDB for my hardware/jailbreak combo? If not how about an active community that might help me figure it out?

I went the route of setting up LLDB and debugserver on my PC but it has the same issue of returning data looking like this

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}

after seeing the latest malware out there affecting even non-jailbroken phones, I would never jailbreak my iPhone.
