I am attempting to use long long's for a 64 bit integer representation of certain data types which are used within various structures in a very large C program. This is on sparc with sunos 4.1.1. I am experiencing various mysterious behavior with this, such as bus errors while initiating allocated (somewhat large) structures containing long longs, at the point where the assignment to the long long is done. Other aspects of initialization within such structures are happy. I tried a simple example which allocated just one such structure, and there was no problem with that. It is very possible that this particular large system has some memory management problems or type un-cleanness which causes these problems; however, the nature of the symptoms does make me suspect possible problems with the memory allocation of these structures containing the long long numbers. If anyone has concrete info on the reliability of this feature and on how much it has been tested, I would like to hear about it. If there is a straightforward way I should be investigating this question, like looking in a topical issue database and or testing histogram or such, do let me know that. Note that this is not really a bug, since I have not reduced this to a definite compiler problem. I'm trying to avoid a lot of tedious debugging in case there are known problems in this department. Thanks. -- Bob Davis -- bobdavis@viewlogic.com
