Merging fun again

[Rick Moseley <rmoseley at redhat dot com>]

Hi Sergio, Tom:

I did a re-merged the archer-tromey-python and 
archer-sergio-syscall-catch branches (with a few difficulties, funny how 
git seemed to work different between an x86 and an x86_64 machine, but 
that's another email) and I have checked this into the 
archer-rmoseley-demo-merge-2 branch.  The purpose was to get the latest 
and greatest stuff both of you guys have checked in.  Unfortunately, 
after the mere and fixing a few problems I am back to square one again 
with *almost* the same problem as the original merge.  The "make check" 
hits a test and gdb eats up all of memory and hard locks the system.  
Here is the output I am seeing when the system locks up:

Running ../.././gdb/testsuite/gdb.arch/powerpc-prologue.exp ...

I'm not sure if this is a real bug or a merge problem is why I posted it 
here.  It may be something very similar to last time.  One of the 
conflicts from the merge was this structure in breakpoint.c:

static const enum bpstat_what_main_action
   table[(int) class_last][(int) BPSTAT_WHAT_LAST] =
 {
 /*                              old action */
 /*       kc    ss    sn    sgl    slr   clr   sr   shl
  */
/*no_effect */
   {kc, ss, sn, sgl, slr, clr, sr, shl, kc},
/*wp_silent */
   {ss, ss, sn, ss, ss, ss, sr, shl, ss},
/*wp_noisy */
   {sn, sn, sn, sn, sn, sn, sr, shl, sn},
/*bp_nostop */
   {sgl, ss, sn, sgl, slr, slr, sr, shl, sgl},
/*bp_silent */
   {ss, ss, sn, ss, ss, ss, sr, shl, ss},
/*bp_noisy */
   {sn, sn, sn, sn, sn, sn, sr, shl, sn},
/*long_jump */
   {slr, ss, sn, slr, slr, err, sr, shl, slr},
/*long_resume */
   {clr, ss, sn, err, err, err, sr, shl, clr},
/*step_resume */
   {sr, sr, sr, sr, sr, sr, sr, sr, sr},
/*shlib */
   {shl, shl, shl, shl, shl, shl, sr, shl, shl},
/* entry_breakpoint */
   {entrybp, entrybp, entrybp, entrybp, entrybp, entrybp, sr, entrybp,
     entrybp}
 };


So, any ideas here?

Thanks,

Rick
