- Compiling various public domain programs on our NeXTstation using the
- 2.1 operating system and gcc as supplied with the machine has revealed
- the following problem. Although the programs invariably pass any test
- routines supplied with the program and will perform correctly in many
- situations, we are plagued with segmentation faults and occasional bus
- errors. Some users have also complained that their programs also
- produce segmentation errors.
-
- I beleive the problem is with memory allocation. We do lengthy
- calculations typically requiring days to complete. One particular
- program has a flag which displays statistics during garbage
- collection. With this flag, we see that just prior to the segmentation
- fault the program does garbage collection almost continually. I do not
- beleive these programs are able to get more memory when they ask for
- it and therefore exit with a segmentaion fault. All of the programs in
- question have been successfully compiled on other platforms without
- adverse behaviour including some of the user's programs. Indeed, all
- of these programs will function properly with "small" inputs but fail
- when attempting the lengthy calculations.
-
- Are we experiencing a known bug? I've looked through the various
- sources of information regarding the NeXT, but haven't found any
- reference to these problems. Any help would be appreciated. I am a
- novice C programmer so I would appreciate less technical responses
- although I would like to understand the technical aspects. There are
- people here who are "real" C programmers however.
