I just wanted to say that I found a solution to this problem (very
simple as well). I defined the try/catch macros as
#define NOPH_try(callback, arg) do { \
asm volatile(""); \
__NOPH_try(callback, arg); \
} while(0); if ( *(int*)0 != 0 ) {
#define NOPH_catch() } do { \
asm volatile(""); \
__NOPH_catch(); \
} while(0)
instead, i.e., adding an if-statement that I know will always be true
and enclosing everything between try/catch in this block.
