I have been having problems compiling some programs with the MPW C 3.0 compiler on my Mac IIx. Specifically, there appears to be a somewhat random occurance of system error 33 while at 'stripaddress+08b4'. Rebooting and recompiling almost always works. I know of other people having similar problems. Is this a known problem ? Does it have a fix/workaround ? Thanks, Brian -- Brian D. Cuthie uunet!umbc3!cbw1!brian Columbia, MD brian@umbc3.umbc.edu

Unfortunately, we don't really know why this happens. It seems to be a problem with the C compiler itself. Somewhere along the way, it randomly trashes a relocatable block header, putting in a funny pattern. We haven't been able to get a reproducable case for this, but recent fixes to the MPW C compiler seem to minimize the effect. If you can help us determine a set of steps we can follow to accurately reproduce the problem, that would help us out immensely! ------------------------------------------------------------------------------ Keith Rollin --- Apple Computer, Inc. --- Developer Technical Support INTERNET: keith@apple.com UUCP: {decwrl, hoptoad, nsc, sun, amdahl}!apple!keith "Argue for your Apple, and sure enough, it's yours" - Keith Rollin, Contusions

Rebooting fixes it. My SCM person just has gotten used to rebooting the machine several times during a build for me, sometimes killing off bad object files that didn't get flushed to disk. I can't reproduce it in a consistent way either, but my sources (almost 10MB) almost always generate at least one of these errors during a complete build. -- Alan Mimms My opinions are generally Communications Product Development Group pretty worthless, but Apple Computer they *are* my own...
