Renderer info:

GL_VENDOR:Intel
GL_RENDERER:Intel(R) HD Graphics 3000
GL_VERSION:3.1.0 - Build 8.15.10.2696

Description:

Code crashes somewhere in glCompileShader. Any whitespace characters after #endif prevents crash.

Code:


std::string shader_src = 
 "#ifdef DEFINED\r\n"
 "out vec4 position;\r\n"
 "void main() {position = vec4(1.0,1.0,1.0,1.0);} \r\n"
 "#else\r\n"
 "out vec4 position;\r\n"
 "void main() {position = vec4(1.0,1.0,1.0,1.0);} \r\n"
 "#endif";
std::string head = "#version 130\r\n#define DEFINED 1\r\n";

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

const char* sources[] = {head.c_str(), shader_src.c_str()};
gl::GLint lens[] = {head.size(),shader_src.size()};

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