Consider the following code:
systab->lockstart =
(void *)((void *)systab->jobtab + (sizeof(jobtab)*jobs)); //locktab
systab->locksize = locksize; // the size
systab->lockhead = NULL; // no locks currently
systab->lockfree = (locktab *) systab->lockstart; // free space
systab->lockfree->fwd_link = NULL; // only one
systab->lockfree->size = locksize; // the whole space
and on the last instruction I get a Program terminated with signal 10, Bus
error. If I swap it with the one following (which references the same
structure), I still get the signal 10.
I am currently compiling this with:
-Wall -g -O0 -fvolatile -fvolatile-global -fvolatile-static
What switches do I need to convince gcc version 2.95.2 to evaluate
the pointer (in this case systab->lockfree) before it gets used?
