[Octave-bug-tracker] [bug #44292] Frequent crashes when printing to eps on Windows platform

[Dan Sebald]

Follow-up Comment #20, bug #44292 (project octave):

OK, if that DLL is ruled out, the empty feedback buffer and the bogus image
sizes of the other report would suggest some kind of bad pointer or something.
 That's at least a clue.

A couple days ago I had investigated up to the rend.draw() function because I
couldn't find where "rend" is declared.  (Too many occurrences of "rend".)  I
sort of verified in my mind that the Mesa libraries were correctly used in the
initialization step.  I'm already getting a crash with


  // Test for a bug in OSMesa with version < 9.0
  //
  // Unfortunately the macros OSMESA_MAJOR_VERSION and
  // OSMESA_MINOR_VERSION weren't updated between many releases and
  // can't be used for detection.  (Version 8.0 until 9.1.4 all return
  // MAJOR 6, MINOR 5)
  int z, s;
  glGetIntegerv (GL_DEPTH_BITS, &z);


but I have 7.4 (although that shouldn't cause a crash, plus I can skip this
step) and can't compile 9+ series right now.  I suppose I could try at least
compile the 8.0 series of Mesa and see if that gets any further.
