I'm running Edition VII Workbench (with source) on a Perkin-Elmer
3220 system. This is basically UNIX v7.
I just got bitten by what I consider a compiler bug. I changed
a number of "int" declarations to "register" in a program I was
making some changes to, not realizing that one of them had its
address used (i.e., "int status" ... "wait(&status)").
Now, I don't mind if the compiler gives me an error, and I don't
mind if it decides that "status" can't be a register after all
and puts it in memory. Either of these is consistent with K&R
pp. 81 and 193, which state that one cannot take the address of
a register.
What I didn't care for is the compiler accepting the code, then
having the program dump core at run-time. Does anyone have a fix
to the v7 compiler which would handle this, or can someone at least
point me at how to solve it? Thanks.
