When I compile my project. Errors as below show up.
app.C(1025): error C253: '?L0033': INTERNAL ERROR (UNDEFINED LABEL) app.C(1025): error C253: '?L0032': INTERNAL ERROR (UNDEFINED LABEL) app.C(1025): error C253: '?L0031': INTERNAL ERROR (UNDEFINED LABEL) app.C(1025): error C253: '?L0046': INTERNAL ERROR (UNDEFINED LABEL) app.C(1025): error C253: '?L0046': INTERNAL ERROR (UNDEFINED LABEL) app.C(1025): error C253: '?L0046': INTERNAL ERROR (UNDEFINED LABEL) app.C(1025): error C253: '?L0046': INTERNAL ERROR (UNDEFINED LABEL) app.C(1025): error C253: '?L0034': INTERNAL ERROR (UNDEFINED LABEL) app.C(1025): error C253: '?L0040': INTERNAL ERROR (UNDEFINED LABEL) app.C(1025): error C253: '?L0040': INTERNAL ERROR (UNDEFINED LABEL) app.C(1025): error C253: '?L0040': INTERNAL ERROR (UNDEFINED LABEL) app.C(1025): error C253: '?L0040': INTERNAL ERROR (UNDEFINED LABEL)
If I build the project again after these errors shows up, it builds successfully. What are these errors and how can I resove them?
Thank you all very much.
As you say yourself, it is nonsense!
What optimisation level are you using? Your example contains unreachable code, so it could be that the optimisations are getting confused by that...?
Have you looked at the generated assembler?
