I was using GDB to debug an executable that used C library functions, but
wasn't linked agianst the C library.  Knowing a fair bit about Darwin, I typed:

  (gdb) set environment DYLD_INSERT_LIBRARIES -lSystem
  (gdb) run

GDB printed

  Starting program: /Users/sam/perl-5.9.2/gdbbug 
  dyld: could not load inserted library: -lSystem

  /SourceCache/gdb/gdb-413/src/gdb/macosx/macosx-nat-inferior.c:1507: 
internal-error: assertion failure in function "macosx_ptrace_him": 
macosx_status->stopped_in_ptrace || macosx_status->stopped_in_softexc

  A problem internal to GDB has been detected,
  further debugging may prove unreliable.

I ran gdb with the normal `gdb executable' command.  My system:

  GDB version: GNU gdb 6.1-20040303 (Apple version gdb-413)
  OS: Darwin
  Kernel version: 8.1.0
  Processor: PowerPC
  Hardware: Apple iBook G4 (from label on physical system, though
`uname -m' says ``Power Macintosh'')
  Mac OS X release: 10.4.1 (``Tiger'')

A sample executable that triggers this bug can be generated by:

  gcc gdbbug.c -o gdbbug
  ld gdbbug.o -o gdbbug -undefined suppress -flat_namespace
  chmod 755 gdbbug

The source file `gdbbug.c' contains:

  #include <stdio.h>
  int foo = 1;
  int doit(void) { printf("Hello World!\n"); return 0; }
