Incorrect results may occur with side effects in logical expressions.
Steps to Reproduce:
[ANSI]
1. Compile with 'bcc32 -tWC bob13954.cpp'; ignore warning.
2. Run 'bob13954.exe'.  Output is:

(PASSED) f_5_16X16: X_5_16X16::dtor == 0
(PASSED) f_5_16X16: X_5_16X16::dtor == 0
(FAILED) ~X_5_16X16: z_5_16X16.xi == 0
(FAILED) f_5_16X16: X_5_16X16::dtor == 1
(PASSED) ~X_5_16X16: z_5_16X16.xi == 3
(PASSED) ~X_5_16X16: z_5_16X16.xi == 3
(PASSED) ~X_5_16X16: z_5_16X16.xi == 3
(PASSED) ~X_5_16X16: z_5_16X16.xi == 3
(PASSED) ~X_5_16X16: z_5_16X16.xi == 3

-------------------------------
the two 'failed' lines should read:

(PASSED) ~X_5_15X22: z_5_15X22.xi == 3
(PASSED) f_5_15X22: i==3, X_5_15X22::dtor == 0
