- Reply-to: gcc-bugzilla at gcc dot gnu dot org
When building gcc I get this during the build of the gnattools:
"Unable to coalesce ssa_names 96 and 455 which are marked as MUST COALESCE.
first_with_96(ab) and first_with_455(ab)"
I do not know the Ada Language, just trying to build it and email
the Testsuite results. I Googled and checked the mailing list for
this Bug without success. Now I'll go check the revisions and see
if I can determine when this failure first occured.
