The way for you to narrow down the bug is this:

1. Compile with -daAP
2. Look in the .s file which instruction references the missing label. There
should be a LABEL_REF with a number.
3. Grep for "code_label.*<number>" in the RTL dumps.  The label should at least
appear in the .expand dump.

This will help you find the pass during/after which the label disappears.
