(Debian bug #283835)
package Test_133 is
package pak1 is
type T1 is null record;
end pak1;
package pak2 is
subtype boolean is standard.boolean;
function "=" (x, y: pak1.T1) return boolean;
end pak2;
use pak1, pak2;
x1: pak1.T1;
b1: boolean := x1 /= x1; --ERROR: ambigous (gnat misses)
b2: boolean := x1 = x1; --ERROR: ambigous
end Test_133;
The actual output from gnat is:
test_133.ads:15:22: ambiguous expression (cannot resolve ""="")
test_133.ads:15:22: possible interpretation at line 8
test_133.ads:15:22: possible interpretation in package Standard
gnatmake: "test_133.ads" compilation error
Only the second error is detected; the ambiguity of "/=" goes
unnoticed.

Summary: Illegal program not detected, "/=" when "=" is ambiguous
