--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> --- (In reply to Fedor Bobkov from comment #2) > Thread-starting example is intended only for demonstration of out of memory > error on simply example. In real projects out of memory error occurs with > much smaller loops which just use bigger amount of data. > > I had got this error on compile-time bilinear downscaling of signed distance > field image. May be it is not proper way to use constexprs but it is very > useful in embedded applications (with small RAM and big ROM (flash) memory). Can you please elaborate it more? We're interested in a test-case for that ;)
