This is taken from your code:<\/p>\n

char *compar;\nif(i==0){\n    sprintf(&compar,\"%c%c%c%c\",code[0],code[1],code[2],code[3]);\n}\n<\/code><\/pre>\n
The problem here is that you declare compar<\/code> as a pointer to char<\/code>, but it is uninitialized. So, it has an undefined value. When you fill it with sprintf<\/code>, you just write somewhere in the memory, and apparently, you write over the variable nombre_instruction<\/code>. <\/p>\n

char compar[200]; \n<\/code><\/pre>\n<\/p><\/div>\n
