           Summary: d3d[89]/tests/visual crash under valgrind
           Product: Wine
           Version: 1.1.34
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: download, source, testcase
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dank at kegel.com


http://kegel.com/wine/valgrind/logs/2009-12-05-01.15/vg-d3d8_visual.txt
and
http://kegel.com/wine/valgrind/logs/2009-12-05-01.15/vg-d3d9_visual.txt
both show the crash

Unhandled exception: page fault on read access to 0x58469450 in 32-bit code
(0x0d9bc92b).
Backtrace:
=>0 0x0d9bc92b (0x11ad7000)
  1 0x0fa16d50 in libgl.so.1 (+0x3dd50) (0x0ffbc038)

which might be a problem in the driver, but could also be a disagreement
between valgrind and the driver.

I'm going to stop running d3d[89]/tests/visual under valgrind for now,
since they always crash.  Perhaps the good folks at Nvidia could
have a look at how to get valgrind and their drivers to play nice together.
(One of those logs also seems to have found a real use-after-free bug
in their driver:
 Invalid read of size 4
    at  ??? (in /usr/lib32/libGLcore.so.180.44)
  Address 0xe6905f4 is 156 bytes inside a block of size 632 free'd
    at  free (vg_replace_malloc.c:325)
    by  ??? (in /usr/lib32/libGLcore.so.180.44)
 so perhaps they would actually get something out of this.)
