I have an application that runs with XFree86. At the beginning of the application, we have Motif do some resource management and then add some signal handlers. If we add a -xrm option to the command line and then initialize with signal(SIGSEGV, function); we see a Bus Error at run time. The Bus Error occurs in the signal call. If we leave the -xrm option off, then we have no problems. Is there some way I can try and chase down the problem in signal? This same exact code runs fine on OS 10.1.5 as well as just about every other UN*X out there. I'm figuring it has to be a problem within OS 10.2 Maybe I have the same signal question like top, but I don't know what is -xrm setting and how to set it in max os? Thanks in advance.
