  10 Due to a kernel bug (kern/35175), detaching from an attached process
  11 will very likely cause the process to be stop or die with a Trace/BPT
  12 trap.

  15 i386-*-freebsd[34]*
  16 -------------------
  17
  18 There is a bug (bin/41671) in FreeBSD's gcc that causes it to emit bad
  19 debug information when using the stabs format (which is the default).
  20 As a result GDB tends to place breakpoints on functions before the
  21 function prologue, and information about function parameters and local
  22 variables is lost.  In earlier versions of GDB the effects were rather
  23 limited, but starting with GDB 5.3 the influence is much more
  24 prominent.  As a workaround, compile your code with -gdwarf-2.

  28 --------------------
  29
  30 gdb/487: The top level make files used to build GDB are not compatible
  31 with HP/UX make.  As a workaround, use GNU make.
  32
  33 gdb/486: The HP/UX C compiler defaults to K&R mode but GDB only builds
  34 with an ISO C compiler.  The top level configuration incorrectly sets
  35 CC to `cc' instead of `cc -Ae'.  As a workaround, the correct compiler
  36 can be specified as part of the configuration vis:
  37
  38     $  'CC=cc -Ae' ./configure

  42 ---------
  43
  44 gdb/513: GDB does not build on s390 GNU/Linux.  The problem should be
  45 fixed in more recent sources.

  50
  51 gdb/455: GDB doesn't build on a FreeBSD 4.4-STABLE system.  The
  52 problem is still being investigated.
