Thanks for your help. I finally found my bug. It was my fault. I 
incorrectly coded:


const pass_data pass_data_chariot_framesize =
{
 Â  GIMPLE_PASS, /* type */ ///@@@@@@@@@@@@ WRONG should be RTL_PASS
 Â  "chariot_framesize", /* name */
 Â  OPTGROUP_NONE, /* optinfo_flags */
 Â  TV_NONE, /* tv_id */
 Â  PROP_ssa, /* properties_required */
 Â  0, /* properties_provided */
 Â  0, /* properties_destroyed */
 Â  0, /* todo_flags_start */
 Â  0, /* todo_flags_finish */
};

and then I inserted such a wrong pass (it is not possible to insert a GIMPLE_PASS after an existing RTL_PASS).

However, the result error message is very cryptic:

cc1: fatal error: pass ‘pro_and_epilogue’ not found but is referenced by 
new pass ‘chariot_framesize’


perhaps the error message should mention a type mismatch.


Thanks for your help.


Cheers
