Subject: [Bug ada/17954] New: Legal program rejected, packed array of booleans
Date: Tue, 12 Oct 2004 18:54:00 -0000 [thread overview]
Message-ID: <20041012185408.17954.ludovic.brenta@insalien.org> (raw)
Debian Bug #276227:
-- interestingly, the error message is different depending on
-- the number of enumeration elements in T1 and T2.
package Test_124 is
type T1 is (b01,b02,b03,b04,b05,b06,b07,b08,b09,b10,
b11,b12,b13,b14,b15,b16,b17,b18,b19,b20,
b21,b22,b23,b24,b25,b26,b27,b28,b29,b30,
b31,b32);
type T1_arr_unconstrained is array (T1 range <>) of boolean;
type T1_arr_constrained is new T1_arr_unconstrained (T1);
pragma pack (T1_arr_unconstrained);
for T1_arr_constrained'size use 32; -- line 12
type T2 is (b01,b02,b03,b04,b05,b06,b07,b08,b09,b10,
b11,b12,b13,b14,b15,b16,b17,b18,b19,b20,
b21,b22,b23,b24,b25,b26,b27,b28,b29,b30,
b31); -- one fewer than T1
type T2_arr_unconstrained is array (T2 range <>) of boolean;
type T2_arr_constrained is new T2_arr_unconstrained (T2);
pragma pack (T2_arr_unconstrained);
for T2_arr_constrained'size use 32; -- line 22
end Test_124;
The actual output from GCC 3.4.2 is:
test_124.ads:12:04: size given for "T1_arr_constrained" too small
test_124.ads:12:04: explicit pragma Pack is required
gnatmake: "test_124.ads" compilation error
If line 12 is commented out:
test_124.ads:22:36: size for "T2_arr_constrained" too small, minimum allowed is 248
gnatmake: "test_124.ads" compilation error
