#11784: panic "hscCmmFile: no_mod" with `-v2 and above -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: patch Priority: high | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2864 Wiki Page: | -------------------------------------+------------------------------------- Comment (by Ben Gamari ): In [changeset:"222e99d9e6b24c17a67c07d24d05999701b83e96/ghc" 222e99d9/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="222e99d9e6b24c17a67c07d24d05999701b83e96" Make up a module name for c-- files Summary: We used to pass a bottoming Module to the NCG, which resulted in panics when `-v` was used due to debug output (see #11784). Instead we make up a module name. This is a bit scary since `PIC.howToAccessLabel` might actually use the Module, but if it wasn't crashing before I suppose it's fine.
