            Bug ID: 3038
           Summary: Conflicting types of tls_in caused by hctx typedef
           Product: Exim
           Version: 4.96+
          Hardware: x86
                OS: All
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Eximon
          Assignee: unallocated@???
          Reporter: mt@???
                CC: exim-dev@???


When linking eximon.bin, type-conflicting definitions of `tls_in` are seen by
the linker. This is caused by the resume_hctx member having different sizes,
which in turn is caused by having conflicting type declarations of `hctx`.
`em_hdr.h` declares: `typedef void * hctx;` when this is a struct in
`src/hash.h`.

The comment in `em_hdr.h` suggests that the full definition is not wanted. I
don't have a good enough understanding to see why `tls_in` needs to be defined
in `em_globals.c` in the first place, but if it is needed it will be of the
wrong size for what the actual uses expect.

Best,
Michael
