Crash in glslang_program_SPIRV_generate_with_options in Android (arm64-v8a)
Problem
Compiling the following shader to SPIR-V on Android device (arm64-v8a) leads to crash in compiler.

void main() {
vec4 c = in_color * texture(sampler2D(kTextures2D[in_textureId], kSamplers[0]), in_uv);
// Render UI in linear color space to sRGB framebuffer.
out_color = kNonLinearColorSpace ? vec4(pow(c.rgb, vec3(2.2)), c.a) : c;

Is there any way you can run this under valgrind or ASAN or some other memory checking program? We tried to reproduce this but have not been able to do so thus far.
@arcady-lunarg Do you mean you tried to reproduce it under ASAN and it didn't reproduce on your Android?
