Hi,
I've fixed the persistent Nasal/IRIX bug in CVS. It turned out to be the
PUSH(r) macro in code.c:
# define PUSH(r) do { \
if(ctx->opTop >= MAX_STACK_DEPTH) ERR(ctx, "stack overflow"); \
ctx->opStack[ctx->opTop++] = r; \
} while(0)
changing it to the following resulted in a working version for IRIX:
# define PUSH(r) _PUSH((ctx), (r))
void _PUSH(struct Context* ctx, naRef r) {
if(ctx->opTop >= MAX_STACK_DEPTH) ERR(ctx, "stack overflow");
ctx->opStack[ctx->opTop++] = r;
}
At first I thought maybe the 'do {...} while(0)' section was optimized
away (a bug in the compiler) but changing it to just '{...}' didn't work
either.
The only thing I can think of right now is that inside the function the
code is working with a *copy* of r
I'm puzzled.
