Adding more frames makes more of it work for me:

opsy. ./install/bin/fdtrace ./Closer
bad close() call at:
at 0x45bdc402
at 0x80483ba in function: doit2 (/home/tromey/gnu/frysk/CC.c:11)
at 0x80483dd in function: main
at 0x45c0f724
at 0x8048301

I've appended the program.

The doit2 frame is nearly correct -- the line number is off by 2.  The
doit frame itself doesn't print any info, and the main frame only
prints the function name.

This is the output including my patch to add StackFrame.toString,
which omits info that it can't find.

Tom

#include <unistd.h>
#include <stdio.h>

void doit() {
  close(73);
  close(74);
}

void doit2() { doit(); }

int main() {
  doit2();
  return 0;
}
