<pre>-----> Actual behaviour:
~/dev/llvm/tools/lldb/test/functionalities/inferior-assert$ ulimit -c unlimited
~/dev/llvm/tools/lldb/test/functionalities/inferior-assert$ ./a.out
~/dev/llvm/tools/lldb/test/functionalities/inferior-assert$ lldb a.out -c core
Core file '~/dev/lldb/tools/lldb/test/functionalities/inferior-assert/core'

-----> Expected behaviour:
libc.so.6`raise + 53:
-> 0x7fee04de7425: cmpq $-0x1000, %rax
0x7fee04de742b: ja 0x7fee04de743f ; raise + 79
0x7fee04de742d: rep
0x7fee04de742e: ret
(lldb)
Note that the "dissasemble -a" command shows a similar pattern of
misdisassembly.
Reproduced on Ubuntu 12.04 with r190622 of llvm, clang, and lldb.</pre>
