Sometime in the last month lldb on FreeBSD reports this error, although the
breakpoint actually does get set.

Using the dictionary.c example / tutorial code,

feynman% bin/lldb /tank/emaste/src/snippets/dictionary
Current executable set to '/tank/emaste/src/snippets/dictionary' (x86_64).
(lldb) b find_word
warning: failed to set breakpoint site at 0x400e60 for breakpoint 2.1: failed
to verify the breakpoint trap in memory.
(lldb) run romeo-and-juliet.txt
Process 75214 launched: '/tank/emaste/src/snippets/dictionary' (x86_64)
Dictionary loaded.
Enter search word: Romeo
Process 75214 stopped
