This is tricky;
C code simulation;
Must not be overwritten;

unsigned char buf[] = "Leave me be";

unsigned char buf[] =
"Do not touch"
"This buf"
;

//right before
    unsigned char buf[] =
"\x91\x25\xee\x89\x9d\x85\xa1\x6d\x6d\x6d\x2c\x3c\x2c\x3d\x3f"
"\x91\x25\xee\x89\x9d\x85\xa1\x6d\x6d\x6d\x2c\x3c\x2c\x3d\x3f"
"\x91\x25\xee\x89\x9d\x85\xa1\x6d\x6d\x6d\x2c\x3c\x2c\x3d\x3f"
"\x91\x25\xee\x89\x9d\x85\xa1\x6d\x6d\x6d\x2c\x3c\x2c\x3d\x3f"
;
// right after


But the shellcode must be overwritten and extended.

unsigned char buf[] = "Leave me be";

unsigned char buf[] =
"So not touch"
"This buf"
;
