Karol Herbst's fuzzing efforts discovered that we would hit the following assert: assert(dummy_instructions.is_empty()); when processing an illegal array size expression of float[(1=1)?1:1] t; In do_assignment, we realized we needed an rvalue for (1 = 1), and generated a temporary variable and assignment from the RHS. We've already flagged an error (non-lvalue in assignment), and return a bogus value as the rvalue. But process_array_size sees the bogus value, which happened to be a constant expression, and rightly assumes that processing a constant expression shouldn't have generated any code. instructions. To handle this, make do_assignment not generate any temps or assignments when it's already raised an error - just return an error value directly.

File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see http://www.mesa3d.org/repository.html - run scons General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
