xCode 4.3 crashes on pause or breakpoint

I have an app running on xCode 4.2 without any issues.

Installed xCode 4.3, ran the application and after tweaking the project settings got it working on both.

I added a breakpoint, upon hitting the breakpoint then running again I get a EXC_BAD_ACCESS at the top of the stack on THREAD 1 in the following code section :

0x28d0:  pushl  $0
0x28d2:  movl   %esp, %ebp
0x28d4:  andl   $240, %esp
0x28d7:  subl   $16, %esp
0x28da:  movl   4(%ebp), %ebx
0x28dd:  movl   %ebx, (%esp)
0x28e0:  leal   8(%ebp), %ecx
0x28e3:  movl   %ecx, 4(%esp)
0x28e7:  addl   $1, %ebx
0x28ea:  shll   $2, %ebx
0x28ed:  addl   %ecx, %ebx
0x28ef:  movl   %ebx, 8(%esp)
0x28f3:  movl   (%ebx), %eax <- EXC_BAD_ACCESS (code=1, address=0xe364d528)
0x28f5:  addl   $4, %ebx
0x28f8:  testl  %eax, %eax
0x28fa:  jne    0x28f3                   ; start + 35
0x28fc:  movl   %ebx, 12(%esp)
0x2900:  calll  0x2910                   ; main at main.m:11
0x2905:  movl   %eax, (%esp)
0x2908:  calll  0x26089a                 ; exit
0x290d:  hlt

This happens at any breakpoint, anywhere, any thread. It also happens when I pause and try to continue, it also happens when I try to step over/in any line of code.

Ideas on why this is happening and how to resolve it?

This might solve your problem. It sounds similar to my issue, except that for me Xcode as a whole was crashing, not just the app. The fix outlined in that question worked for me.

I switched the debugger from LLDB back to GDB under Schemes and it doesn't crash every time now.
