From: Eric Botcazou <ebotca...@adacore.com> The compiler reports that an actual does not match the formal when there is a defaulted formal discrete type because Check_Formal_Package_Instance fails to skip the implicit base type generated by the compiler.
gcc/ada/ChangeLog: PR ada/114636 * sem_ch12.adb (Check_Formal_Package_Instance): For a defaulted formal discrete type, skip the generated implicit base type.
