Package: gnat-7 Severity: minor Hello.
The fix for #856042 lets gnat write a fake time stamp into the .ali file when an Ada source is more recent than SOURCE_DATE_EPOCH. If another source depending on this one is later compiled with gnatmake, gnatmake will (sensibly) conclude that the dependency must be recompiled. Each recursive reverse dependency then triggers a recompilation of the same source. A reproducer is attached. As long as no proper fix is found, the -m gnatmake/gprbuild option circumvents the issue.
