             Bug #: 48535
           Summary: Spurious GL_INVALID_OPERATION error generated by
                    glColor()
    Classification: Unclassified
           Product: Mesa
           Version: 7.10
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: minor
          Priority: low
         Component: Drivers/DRI/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: i.am.inuyasha@gmail.com

Program that reproduces the issue

In some unknown circumstance glColor() can raise a GL_INVALID_OPERATION error,
which according to the manual should never happen. The attached program
reproduces the issue. It's generated from a log of GL calls made by another
program, so it's quite long (and some texture-related commands have been
stripped out, which I verified does not affect the result). The output I get
is:

Error 1282 at line 7353

which is consistent with the original program's issue - glColor() suddenly
raises this error after making all these GL calls.

What card and version of mesa are you using?  Please attach your xorg log and
dmesg output.

I guess it's a mesa core problem. Debug build of the mesa also prints the
following error message when running the attached test app:

"Mesa: User error: GL_INVALID_OPERATION in Inside glBegin/glEnd"

It's printed from the ASSERT_OUTSIDE_BEGIN_END_WITH_RETVAL macro in the
_mesa_GetError(), called from gl-bug.c:6823. Though it's not inside Begin/End.

Probably the error reported later after the glColor call at the line 7353 is
just a consequence of the real bug somewhere in the display list handling.
