Title:
  Crash during optimize (Mac Leopard)

Status in Hugin - Panorama Tools GUI:
  Expired

Bug description:
  After loading images and lens data, Hugin hangs and then crashes
  pretty much every time I click the "Optimize now!" button (or during
  the optimize step of the Assistant's "Align" step).  It's possible
  this bug is in one of the libraries used by Hugin, but I figure I
  should report it here first.

  I have seen this behavior every time I attempt to use Hugin on my PPC
  G4 Mac laptop and at least some of the time when testing on an Intel
  iMac, both running Mac OS 10.5.8.  I first saw the error on my PPC
  while using Hugin 0.6.1 (it's been a while since I last used the
  program; I've upgraded from 10.3 to 10.5 since the last time I used it
  successfully), but I am getting similar crash logs with 0.8.0 on both
  PPC and Intel platforms (I've tried several different precompiled
  binary packages linked from the Hugin site).  I've observed it on the
  PPC in two or three entirely different panorama stitching projects
  (with two or three images each, one of which had worked when I first
  tried it a year or two ago) and on the Intel during one attempt to do
  perspective correction on a single image (a later attempt worked for
  that one; I don't know what could have changed).

  I'm attaching a crash reporter log from my Intel iMac, which shows the
  characteristic signature that I've seen on both machines: a crash in
  Thread 0, with a variety of addresses at the top of the stack (in this
  case, 0x160243c8, but sometimes just 0 or 0xc0000000).  The key points
  of commonality are the top few stack lines:

  0   ???                                 0x160243c8 0 + 369247176
  1   libSystem.B.dylib                   0x96733cb4 setlocale + 945
  2   libpano13.dylib                     0x003b5e6c ParseScript + 44
  3   net.sourceforge.hugin.base_wx       0x0157aad2 HuginBase::PTools::optimize(HuginBase::PanoramaData&, char const*) + 82
  ...

  The "setlocale" function called by "ParseScript" called by "optimize"
  is always the same.  For what it's worth, I've sometimes also run
  Hugin from the terminal on my PPC, and very early in the optimizing
  process I see a message like:

  "Hugin(750,0xa0ab6820) malloc: *** error for object 0x2237a00: double free
  *** set a breakpoint in malloc_error_break to debug"

  which appears even before all the "Optimizing variables:" steps are
  printed.  But after optimization gets the distance down to a
  respectable size, program execution just ends with a seg fault or bus
  error (and Apple's crash reporter dialog box, eventually).

  This is frustrating, because it makes Hugin entirely unusable on my
  PPC laptop and (I expect) frustrating to use much on my Intel iMac.  I
  hope you can track it down!
