What is up with the size of jmp_buf?
It appears that setjmp.h confuses bytes and ints, specifically in the Cygwin
case.
_JBLEN should be 13, not 13*4.
or #define _JBTYPE to char, but that doesn't work as easily.
?
I applied a local hack workaround, something like:
typedef unsigned char JBTYPE __attribute(align(4));
#define _JBTYPE _JBTYPE
#include
Though my larger goal, of implementing (deprecated-in-favor-of-pthreads) Posix
get/make/set/swapcontext I gave up on anyway, at least via layering over
setjmp/longjmp. They may be implementable via Win32 fibers, though the overall
thing still perhaps dodgy and useless ("user more threads"...).
I realize that jmp_buf is something "deep" and system specific, not to be
messed with lightly, but I'm also pretty darn certain that Cygwin declares its
own jmp_buf incorrectly.
I also realize that larger than needed is safe, "just" wasteful, and possibly
"future proof".
It still seems like a mistake.
