Description

Original code:

long l_l = (2);

Decompiled code:

void* v4;  // [bp-0x18], Other Possible Types: unsigned long long, unsigned long
v4 = 2;

It show this variable may be a long integer, but I wonder why angr eventually considers it as a pointer.

Steps to reproduce the bug

Files:
4.zip

(0. the exec is included as orig_exec)

  1. compile orig,c into a Mach-O exec (I used OS X Cross on Linux) with Clang and -O0.
  2. decompile the exec with angr.
  3. the issue is at the beginning of the second function (original name func_1 is not recovered).
