    I have recently been having some big problems passing pointers in VMS C. 
Consider the following:

char *wr(a)
int a;
{ body }

main()
{
 printf(" %s ",wr(4));
}

    This compiles and links without any problems, but I get a stack dump when 
I run it. The same is true of the following:

main()
{
 char b[12];

 b[0]='A';
 strcpy(((&b)+1),"rf!");
 printf(" %s ",b);
}

    Once again it compiles and links without warning, but dumps the stack upon 
execution. I checked my trusty K&R (less trusty by the day, it seems), which 
said that this should be correct.
    I am working in VMS 4.7 . Under this version we must link to 
SYS$SHARE:VAXCRTL.EXE/SHARE instead of the default library. Has anyone else 
had this problem, and if so, what can be done about it? At present I am living 
in fear of library calls that I thought were legal.
