Comment(by whiteknight):
Infinoid: I think you're right about your analysis of this function. At
the least, it's the same conclusion that I came to. getcontext() should be
returning the processor register set into a variable on the call stack for
later scanning by the GC. I also share your concern that this variable is
likely to get optimized away. I don't have an HPUX platform to test on,
but I strongly suspect this is the case.
I'm in the middle of some GC-related cleanups and the mess in
src/gc/system.c is high up on my priorities list. One potential quick-fix
solution would be to mark the variable as "volatile", although the
compiler might complain that marking a local variable like that as
volatile is nonsensical. I've got some better, more in-depth ideas for
fixing this permanently, but if this is giving a problem the "volatile"
keyword might just make it go away.
Anyway, that's me going off on a tangent. The GC is getting all cleaned up
soon so don't worry about these issues unless they are causing a major
problem.
