[Bug Report] GLSL compiler crashes when glsl code ends with # endif

idata — Tue, 24 Apr 2012 13:32:55 GMT

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);
