Hi all,
I've been running with code checked in Mesa tree and there appears to be
rather large memory leak which can be plainly seen by running glxgears and
watching top.
One more piece of information - the memory leak increases with the size of
the window. This is very surprising as I did not think window size should
matter.
Also, the code path pointed by Valgrind does not appear to cause this, at
least not in the obvious way - putting printf("Hello\n") in r300NewProgram
does not print many "Hello"'s so this is not the actual culprit..
Does anyone have suggestions ?

Valgrind says it is caused by:

of 55

So apparently we never free programs..
Also, there is a small leak in DRI Hash code:
