Bug ID: 116644 Summary: Warnings in generic code don't report column number Product: gcc Version: 14.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: ada Assignee: unassigned at gcc dot gnu.org Reporter: mytbk920423 at gmail dot com CC: dkm at gcc dot gnu.org Target Milestone: --- When compiling the following Ada code, GCC gives a warning with the correct line number, but doesn't have the column number in it, which is insufficient for me to find the bug in the code. code: -- gen_testpkg.ads generic type T is mod <>; package Gen_Testpkg is function Test_Mod(A : T) return T; end Gen_Testpkg; -- gen_testpkg.adb package body Gen_Testpkg is function Test_Mod(A : T) return T is type U8 is mod 256; Map : constant array (U8) of U8 := (1, 3, 5, others => 0); begin return T(Map(U8(A mod 256))); -- ^^^ -- If T'Modulus <= 256, then 256 is not in range of type T -- We can use U8'Mod(A) instead end Test_Mod; end Gen_Testpkg; -- test_generic.adb with Gen_Testpkg; procedure Test_Generic is type My_Byte is mod 256; package My_Pkg is new Gen_Testpkg(T => My_Byte); begin null; end Test_Generic; warning: test_generic.adb:6:03: warning: in instantiation at gen_testpkg.adb:8 [enabled by default] test_generic.adb:6:03: warning: value not in range of type "My_Byte" defined at line 5 [enabled by default] test_generic.adb:6:03: warning: Constraint_Error will be raised at run time [enabled by default]
