gcc internal failure during optimization delete_trivially_dead_insns

[ftwilliam]

Hi Jeff,

Thank you very much for your help.

Defining EH_RETURN_DATA_REGNO solved the issue.

I am now getting a different error; I tried googling around without
success, and I am newbie at GCC internals.

I am opening a new thread which will be titled "SIGSEGV at
df_ref_record()", to which a patch against trunk will be attached.

I would very much appreciate your help.
