Date: Thu, 02 Jan 2003 21:21:00 -0000 [thread overview] Message-ID: <4.3.2.7.2.20030102162123.020738d8@toque.cisco.com> (raw) Hi there, It appears to be a bug to me. * gcc version: gcc.c2.95.3 * source code: bug.c #include<stdio.h> int main(void) { int r, i; i = 0; r = ++i % 2; printf("test 1 : r = %d, i = %d\n", r, i); i = 0; r = i++ % 2; printf("test 2 : r = %d, i = %d\n", r, i); i = 0; r = (++i) % 2; printf("test 3 : r = %d, i = %d\n", r, i); i = 0; r = (i++) % 2; printf("test 4 : r = %d, i = %d\n", r, i); i = 0; r = (i+1) % 2; printf("test 5 : r = %d, i = %d\n", r, i); return 0; } * compile command: gcc.c2.95.3 bug.c * type of machine: SunOS ott-view1 5.6 Generic_105181-28 sun4u sparc SUNW,Ultra-Enterprise ... * output : test 1 : r = 1, i = 1 test 2 : r = 0, i = 1 test 3 : r = 1, i = 1 test 4 : r = 0, i = 1 test 5 : r = 1, i = 0 Expecting r = 1 in test 4, because use of brackets. Thanks, Songtao
