cesar at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Resolution|--- |FIXED --- Comment #6 from cesar at gcc dot gnu.org --- This has been fixed in r232121. I also ended up applying that lto patch to gomp4 because it makes user errors involving undeclared variables and routines more user friendly. I.e., instead of crashing it just reports an error message.
