Summary: Bogus GL_INVALID_OPERATION when calling glGetError
inside glNewList() - glEndList() block with
GL_COMPILE_AND_EXECUTE
Product: Mesa
Version: unspecified
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/X11
AssignedTo: [email protected]
ReportedBy: [email protected]

I can reproduce this bug with Mesa 7.4 indirect (ships with Ubuntu 9.04 x86).
It does not occur on Nvidia or Ati binary drivers.
This is similar to a Mesa bug that was fixed a few years ago:
https://bugs.freedesktop.org/show_bug.cgi?id=7984
According to the specs, the following code should not generate an
InvalidOperation error:
int list = glGenLists(1); glGetError();
glNewList(list, GL_COMPILE_AND_EXECUTE); glGetError();
glBegin(GL_TRIANGLES);
glVertex3f(0, 0, 0);
glVertex3f(1, 0, 0);
glVertex3f(1, 1, 0);
glEnd(); glGetError();
glEndList(); glGetError();
However, the very last call to glGetError() reports GL_INVALID_OPERATION.
