KLEE Crashing on Bitcode While Executing Initial LLVM Passes

[bathooman]

KLEE Version

KLEE 3.0 (https://klee.github.io)
  Build mode: RelWithDebInfo (Asserts: ON)
  Build revision: dfa53ed4f5711ee2d378abb267bff1da8623f7e7

LLVM (http://llvm.org/):
  LLVM version 12.0.0
  
  Optimized build.
  Default target: x86_64-pc-linux-gnu
  Host CPU: ivybridge

Running Command

klee --kdalloc=0 --libc=uclibc --solver-backend=z3 libcoap-standalone.bc

Concise Description

When I execute the attached bitcode, KLEE crashes during executing initial LLVM passes. I appreciate any help on this matter.

libcoap-standalone.zip

Error Output
