guys. I am debugging my project with lldb. And I get an error as follows.
Process 83444 stopped
* thread #2, stop reason = EXC_BAD_ACCESS (code=259, address=0x10080c8e8)
frame #0: 0x00000001001d69e4 libctask.dylib`ct_main(arg=0x0000000100808800) at ctask.c:12 [opt]
9
10 static int
11 ct_main(void *arg)
-> 12 {
13 coroutine *ct = arg;
I find a lot of answers about EXC_BAD_ACCESS, but the error codes are not 259.
Where can I find the docs about this error code?
Or is there are any descriptions about it?
XNU, osfmk/mach/arm/exception.h:
#define EXC_ARM_DA_ALIGN 0x101 /* Alignment Fault */
#define EXC_ARM_DA_DEBUG 0x102 /* Debug (watch/break) Fault */
#define EXC_ARM_SP_ALIGN 0x103 /* SP Alignment Fault */
#define EXC_ARM_SWP 0x104 /* SWP instruction */
#define EXC_ARM_PAC_FAIL 0x105 /* PAC authentication failure */
Your stack pointer is not aligned to 0x10 bytes.
