Created attachment 37656 [details] [review] patch on nurb.c The latest version of software I have is 7.7.1, using i965 driver, ubuntu package. If any nurbs demo is modified so that it is captured in a calllist, then it generates an opengl error when the calllist is invoked, even though there is no error if instead of going to the calllist, the commands are directly executed, or if the GL_COMPILE_AND_EXECUTE mode is set. However in the latter case, the calllist still fails if subsequently executed. attached is a file called local.h, which contains macro definitions to implement test software, and a file called nurb.patch, which is a patch on the file progs/samples/nurb.c in the mesa demos package. To verify that this error does not exist, place local.h in the same directory as nurb.c, apply nurb.patch, compile and run the program. If it fails with the environmental variable DOLIST set to 'y', but otherwise works, then there is no longer any error. The error message GL_INVALID_OPERATION in glEnd generally appears with debugging set. This error also appears with other nurb demos similarly modified, such as nurbs.c, surface.c, and trim.c.
Created attachment 37657 [details] code to implement macros that invoke genlist calls.
This is unlikely to be driver-specific, so reassigning to core.
There is no longer any error generated. Seems to have been fixed some time in the last 9 years :P
