--- Comment #3 from la...@fit.vutbr.cz ---
Patch seems to be ok. I've only changed installed header files in
/usr/local/include/php/Zend, recompiled/reinstalled opcache, restarted apache
and it runs.
I've reduced problem to:
#include <stdio.h>
#include <stdlib.h>
#define EX_TMP_VAR(ex, n) ((temp_variable*)(((char*)(ex)) +
((int)(n))))
#define EX_TMP_VAR_NUM(ex, n) (EX_TMP_VAR(ex, 0) - (1 + (n)))
#define VAR_NUM(v) ((unsigned int)(EX_TMP_VAR_NUM(0, 0) - EX_TMP_VAR(0, v)))
typedef struct TV {
long tmp;
char tmp3[30];
} temp_variable;
int num;
int main()
{
printf("%x\n", VAR_NUM(-100));
return 0;
}
