[comp.sys.mac.system] Gatekeeper 1.2

chrisj@ut-emx.uucp (Chris Johnson) (05/19/91)

Not to detract from the System 7 discussions, but I'd like to ask the
Gatekeeper 1.2 users of this group for some assistance in tracking down an
extremely obscure bug in 1.2 (at least I *assume* the bug is in Gatekeeper,
it's hard to be certain).

The symptom is this:  Gatekeeper 1.2 crashes during startup *before* it can
draw its startup icon.  This is most common when running in 4 color (2 bit
plane) mode.  This bug has only been reported twice, so I'd like to find
other Macs that may be suffering from this problem in order to get a better
idea of what's causing it.  The crash, incidentally, occurs in a CopyBits
call that is attempting to copy the single-bit ICN# mask bitmap to a
GrafPort on the startup screen.

Note that Gatekeeper 1.2 may crash or gracefully refuse to install during
startup due to low memory conditions.  This problem has been corrected. 
Just let me know if you happen to have a Mac on which Gatekeeper 1.2 crashes
*before* it can display its startup icon (or if you have some idea of what
might cause such a crash).

At the moment, I'm bewildered.

Thanks in advance.

P.S.  If you've encountered other bugs, let me know about those too.  Version
      1.2 is an important step in Gatekeeper's evolution.  Future 1.x versions
      (as well as 2.0) will depend heavily on code now in 1.2, so arriving at a 
      thorough understanding of 1.2's behavior is important.  Thanks again.
