gprofng interrupts your application every 10007 msec and collects the stacks.
We see that there are no “*bin2SD” functions.
This means that gprofng did not collect the stack with Fbin2SD.
It's okay if Fbin2SD is that fast.
But this can become a problem when unwinding the stack.
What is an output of:
  gprofng display text -calltree test.1.er


> $ gprofng display text -source Fbin2SD test.1.er
> /usr/bin/gp-display-text: Processed 
> /home/robj/TMP/DesignOfIIRFilters/.gprofng.rc for default settings
> Error: Source location not recorded in experiment

This means that gprofng found Fbin2SD in src/bin2SD.oct, but cannot read DWARF.
you have attached bin2SD.oct.tar.gz. gprofng can read DWARF in this file.
But it looks like a different file (Perhaps it was rebuilt).
Could you attach test.1.er/archives/bin2SD.oct*.
