RXA product settings

Using Mesa 9.0.2 Gallium softpipe or llvmpipe drivers, debug builds on Windows report the following assertion failure:

src\mesa\state_tracker\st_mesa_to_tgsi.c:1256:st_translate_mesa_program: freeing bad or corrupted memory 0x63588d38
src\gallium\auxiliary\util\u_debug_memory.c:160:debug_free: Assertion `0' failed.

This assert fails during the initialization of most GLUT sample programs such as dinospin, gears, bounce, etc.

Mesa 9.0.2 is built with mingw, python 2.7, scons 2.2.0.  Same result with LLVM (llvmpipe) or without it (softpipe).

My steps to reproduce:

1.  Install Attachmate Reflection X Advantage v4.2 (a PC X Server product), available in an evaluation download of the Reflection X 2011 product suite (http://www.attachmate.com/Evals/pc-x-server/rsx2011/portal.htm).
2.  Copy the debug Mesa library into the product install folder:
  from
\Mesa-9.0.2\build\windows-x86-debug\gallium\targets\libgl-gdi\opengl32.dll
  to
\Program Files (x86)\Attachmate\Reflection
3.  Start > All Programs > Attachmate Reflection > X Manager - Reflection X Advantage
4.  Run a debugger, e.g. Visual Studio, and attach to the "rxmgr.exe" process.
5.  In X Manager, import the attached rxa_settings.rxd file.
6.  Click on My Sessions > MWM Session, and click Action > Start.  Enter host name, username, and password for any Linux/UNIX host that has GLUT sample applications (e.g. dinospin).
7.  In the XTerm, run a GLUT application, e.g. dinospin.
8.  Debugger breaks on os_abort() in u_debug.c _debug_assert_fail().  Call stack:
