Question backtrace and backtrace_symbols


I am attempting to generate stacktraces in a thread using the
system calls backtrace and backtrace_symbols

  void *arr[NUM_STACKFRAMES];
  int nSize = backtrace(arr, NUM_STACKFRAMES);
  char **sym = backtrace_symbols(arr, nSize);
  char nl = '\n';
  int ii;
  for (ii = 0; ii < nSize; ii++) {
    SENDTOLOGS(alog,apstklog, &nl);
  return ii;
backtrace_symbols is able to find function names in the
library that has the stacktracing code but is unable to find the
function names in any of our other libraries - backtrace has returned the
correct address.

I used the the flags -rdynamic and -fno-omit-frame-pointer to build
our libraries.

Any suggestions for what I might try ?

Code: [0x2aab5dd9a8] [0x2aab5db13f] [0x2a958de1fe] [0x2a958df77b]
