Georg-Johann Lay <gjl at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED CC| |gjl at gcc dot gnu.org Resolution|--- |DUPLICATE --- Comment #1 from Georg-Johann Lay <gjl at gcc dot gnu.org> --- switch / case won't work with 64-bit values; it's beed fixed for v7. As the changes are intrusive, there are no plans to back-port them, and hence you'll have to resort to <= 32 bits in switch / case if you use v6 or older. *** This bug has been marked as a duplicate of bug 71678 ***
