[Bug Report] GLSL macro causes glsl-compiler freeze

[idata]

OS: Win7 64bit

Renderer info:

GL_VENDOR:Intel

GL_RENDERER:Intel(R) HD Graphics 3000

GL_VERSION:3.1.0 - Build 8.15.10.2761

Description:

Thread never returns from call to glCompileShader.

Code:

//Compiler freezes

std::string macros =

"# version 130\r\n"

"# define TEST_MACRO(X) uniform sampler2D agent_# X\r\n";

std::string source =

"TEST_MACRO(text0);\r\n";

gl::GLint shader = gl::glCreateShader(gl::GL_VERTEX_SHADER);

const char* sources[] = {macros.c_str(), source.c_str()};

gl::GLint lens[] = {macros.size(),source.size()};

gl::glShaderSource(shader,2,sources,lens);

gl::glCompileShader(shader);

Other similar problem:

Description:

Very similar code results compiling error, even thou I think that glsl-shader code is valid.

According to http://www.opengl.org/wiki/GLSL_Object# Shader_compiling http://www.opengl.org/wiki/GLSL_Object# Shader_compiling glShaderSource should work like string given to it are combined.

GLSL code will compile if both source strings are combined before giving them to compiler.

Code:

//Compile fail

std::string macros =

"# version 130\r\n"

"# define TEST_MACRO(X) uniform sampler2D agent_# X; uniform vec4 agent_# X# _atlas_rect\r\n";

std::string source =

"TEST_MACRO(text0);\r\n";

gl::GLint shader = gl::glCreateShader(gl::GL_VERTEX_SHADER);

const char* sources[] = {macros.c_str(), source.c_str()};

gl::GLint lens[] = {macros.size(),source.size()};

gl::glShaderSource(shader,2,sources,lens);

gl::glCompileShader(shader);
