Is there a way to find the source location for that PC address?

Find the solution:

lldb-11 tests_curl
(lldb) target create "tests_curl"
Current executable set to 'tests_curl' (i686).
(lldb) image lookup --address 0x005e34a9
       Address: tests_curl[0x005e34a9] (tests_curl..text + 1975465)
       Summary: tests_curl`getinfo_offt + 1817 at getinfo.c
