Hello, I'm attempting to get the hoc ( high order calculator ) example in Kernighan and Pike's The_Unix_Programming_Environment up and running. I've run into a problem in stage six. When I attempt to run the fib example ( every- thing compiles and links fine ) I get a bus error and core dump. Under dbx, I find the following problem: hoc>dbx hoc6 Reading symbolic information... Read 1358 symbols (dbx) run fib - Running: hoc6 fib - fib(10) signal BUS (alignment error) in execute at line 417 in file "code.c" 417 (*(*pc++))(); (dbx) quit lint tells me that there is possibly an error in pointer alignment in the line yyval.sym = (Symbol *)emalloc(strlen(sbuf)+1) in hoc.y We've compiled and tried to run this code on a Sun4, Sun3, and a microVax, on the chance that this is a portability problem. No such luck; we get the exact same problem in all three cases. All the other examples in the text run ok. Has anyone dealt with this problem before, or have any suggestions? Please reply by e-mail; I'll forward the contents of responses to anyone who is interested, or summarize on the net if there is enough interest. Thanks in advance, Pete Wood e-mail wood@maccs.dcss.mcmaster.ca
