Problems w/ X on openbsd (3.1,2) -current

[elaine forbes <elaine_(_at_)_fwsystems_(_dot_)_com>]

This frist cropped up on 3.1 -stable, I've since updated to 3.2, I've not
seen any recent changes in XF4, and in any case the behavior has not
changed.


Environment, T-23 thinkpad laptop, PIII S3-savage IXC chip / config which 
has been working and stable(sic) on X11 since 4.1.99- (on linux).

Any ideas on the following would be appreciated (either on what's broken
or on how to get better diagnostics)

thanks.      elaine

Description:

2 problems

1. Apps which use hardware accel GL are causing segfaults in X 

>From XFree86.0.log

Fatal server error:
Caught signal 11.  Server aborting


The whole logfile is at:

Running X under gdb I was able to get the following backtrace

#0  0x51a38 in AllocDirect ()

2. Using Enlightenment (e 16.5), color planes available to the WM become
corrupted. Only when using GTK applications. 

This has been true using both 16bpp and 24bpp base resolution.

Using the Imlib config tool to make more memory available seems to have 
helped some but not eliminated the problem. All is fine until 2-3 gtk
applications have been opened and then the color planes become corrupt.

Here are 2 snapshots:

And what the topbar should look like:
