Iain Sandoe <iains at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |evstupac at gmail dot com --- Comment #1 from Iain Sandoe <iains at gcc dot gnu.org> --- confirmed on x86_64-darwin12. this is generating an unnecesary picbase (since it is unused in the function), and thus the thunk - which triggers the failure. This is probably more fallout from the EBX changes.
