This is possibly a bug report.
clBuildProgram() crashes instead of reporting an error when accessing index get_global_id() of an uninitialized pointer. Here is a minimal example in C++:
#define __CL_ENABLE_EXCEPTIONS
#include <CL/cl.hpp>
#include <iostream>
int main(int argc, char** argv) {
try {
std::vector <cl::Platform> platforms;
cl::Platform::get(&platforms);
cl_context_properties properties[] =
{CL_CONTEXT_PLATFORM, (cl_context_properties)(platforms[0])(), 0};
cl::Context context(CL_DEVICE_TYPE_CPU, properties);
std::vector<cl::Device> devices;
devices = context.getInfo<CL_CONTEXT_DEVICES>();
std::string prog_str = "__kernel void minex() { int *x; x[get_global_id(0)] = 0; }";
cl::Program::Sources source(1, std::make_pair(prog_str.c_str(),prog_str.length()));
cl::Program program(context, source);
program.build(devices,""); // SEGV here from clBuildProgram
return EXIT_SUCCESS;
}
catch (cl::Error& e) {
std::cerr << "ERROR: " << e.what() << " - " << e.err() << std::endl;
return EXIT_FAILURE;
}
}
