c-testsuite 00129: goto past declarations + pathological s shadowing + #define s s

• Type: bug (cparser scoping/labels). Track C. Low priority (pathological).
• Found: 2026-07-06 c-testsuite run.

Failing test

• 00129: struct tag s, member s, global s2, #define s s + #undef s, goto s; jumping over struct s s; declaration into a label named s. Error "pascal26:23: error: expected C expression". Tests that tag / member / object / label namespaces are fully separate and goto may skip declarations.

Gate

Drop 00129.c from test/c-conformance/pxx.skip; runner green.

Update 2026-07-07

Status: the COMPILER itself SIGSEGVs while compiling 00129 (pathological #define s s + struct s s var + goto over decls into a label s:). It no longer errors cleanly — it crashes. Low priority (prio 28, pathological); a compiler crash on adversarial input, needs a focused debug (likely the s name colliding across the tag/member/object/label namespaces + the goto-over-declaration jump).
