Should not break with edge cases like the previous ad-hoc approach.

But compilers evaluate `5*0 -> 0` and allow it as if a null pointer literal. cpp: #include MACRO, free tks 2026-03-06T10:47:20+00:00 lemon lsof@mailbox.org 2026-03-06T10:47:20+00:00 urn:sha1:e28b2c8b2b3a059fcab043d5ab91b620c0a4890b c: recognize another static initializer edge case 2026-03-05T18:22:08+00:00 lemon lsof@mailbox.org 2026-03-05T18:22:08+00:00 urn:sha1:25a143d75df857c6b76c67a71a3683d0191c711b I think globsym & expr2reloc should be rewritten to be more robust to this kind of thing. Accumulate offsets whilst recursing into the child node that might contain a direct global symbol reference kind of thing. cpp: get rid of unnecessary ugly global variable for lexing header name 2026-03-05T18:12:44+00:00 lemon lsof@mailbox.org 2026-03-05T18:12:44+00:00 urn:sha1:4362ce9e9d7defddb2d7965ef1cbf481599f5c81 Make it a parameter.
