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.
