gprof with -lc_p: anyone able to do it?

["Paul D. Smith" <psmith@gnu.org>]

I wanted to do some profiling on GNU make, so I installed the libc6-prof
package (I'm using testing) and built make like this:

  $ make CFLAGS='-g -pg' LDFLAGS='-g -pg' LIBS=-lc_p

But this is very unhappy:

  $ ./make
  Segmentation fault

:( :(

GDB says:

  Program received signal SIGSEGV, Segmentation fault.
  0x08099133 in _dl_lookup_versioned_symbol ()
  (gdb) bt
  #0  0x08099133 in _dl_lookup_versioned_symbol ()
  #1  0x40008385 in ?? ()
  #2  0x400029c9 in ?? ()
  #3  0x4000bc29 in ?? ()
  #4  0x4000175a in ?? ()
  #5  0x400016cb in ?? ()

Not very helpful.

Note that if I leave of the C profiling library (no -lc_p) then it works
fine and I can generate profiling output... but when I do that it only
accounts for 18 seconds of a 3+ minute run!

Am I doing something wrong here?

Thanks!
