How do I get a valid backtrace()?

Within my applications, I am needing to be able to generate a valid call stack for reporting purposes.  I do this successfully on my standard x86 based Ubuntu machine using the backtrace() function in concert with backtrace_symbols().  However, when I try to perform the same operations running on the i.MX 6Q Sabre SD, I get mixed results.  Some look valid, but most are incomplete or invalid in some way.  I have tried compiling using -fno-omit-frame-pointer -mapcs-frame -funwind-tables -rdynamic, but nothing seems to affect the output of the backtrace() function.
