Those of you experiencing spurious bus errors under MacBSD (MRG kernel #25,
in my case) may want to check your ADB connections. I was having a
terrible time with gcc while trying to compile some X-Windows software,
because it kept on crashing with signal 10. There were no syntax errors in
the source files; gcc would just bomb at random times. Manually restarting
the make process got to be a real pain.
For unrelated reasons, I happened to replace the original spiral-type ADB
cable with a longer 6-foot cable. The spiral cable was getting stretched
out a bit too much, and was putting a little tension on the ADB port on the
back of my SE/30. Guess what? After replacing the cable, the problems
with gcc went away. The entire build process for XView went without a
hitch.
I can only speculate that the code to handle ADB is a bit weak at the
moment, and the tension on the ADB cable was generating some bogus
interrupts. Of course, I could be totally mistaken. Replies welcome.
-David.
