Summary0000221: Crash when using a large number of shaders.
DescriptionUsing a large number of shaders in MadVR causes a crash. The exact number seems to depend on MadVR settings, and to some degree on the shader. The number of shaders causing a crash seems to get lower by using more complex processing and seems to be at most 28. Render times seem to be irrelevant. Other renderers don't seem to have this issue. Sometimes causes the crash reporter to be called in an infinite loop, making it very hard to stop the program.
Steps To ReproduceUsing default settings, add the following shader
    sampler s0 : register(s0);
    float4 main(float2 tex : TEXCOORD0) : COLOR { return tex2D(s0, tex); }
compiled with either ps_2_0 or ps_3_0, pre or post resize. For 28 times if no resizing and 26 if upscaling/downscaling.
Additional InformationAttached a crash report of a reproduction using the steps described above, no resizing.
TagsNo tags attached.
