It was just a red herring. Having no compiler in the path lead to
HAVE_COMDAT_GROUP not to be defined which change the result of can_alias_cdtor
and thus the number of times a pass is called. Making HAVE_COMDAT_GROUP be
true, I can see there is still a difference in code generation but I guess it's
likely a similar thing. No issue here.

Best regards.
