FPC-conformance long tail: RTL gaps, runtime faults, small parser holes
- Type: task umbrella (catch-all for the audit's small clusters)
- Track: P (frontend) / B (RTL pieces)
- Status: backlog — filed 2026-07-10 from the FPC-testsuite audit ([[feature-pascal-corpus-fpc-testsuite]]).
- Owner: —
The four big clusters have their own tickets ([[bug-pascal-headerless-program]]
111, [[feature-pascal-delphi-generics-syntax]] 93+,
[[feature-pascal-generic-nonclass-templates]] 10,
[[feature-pascal-class-management-operators]] 8,
[[bug-pascal-missing-diagnostics-fail-tests]] 13). This ticket tracks the rest
(reasons verbatim in test/pascal-conformance/pxx.skip):
- RTL gaps (B):
RandSeedflushstringsunitRunErrorUniqueStringHexStr/Lo/Hi/Swap/EraseExitCode(NOT a plain var — needs finalization execution + Halt semantics, split to [[feature-pascal-exitcode-finalization-halt]], Track A),LowerCase,DynArraySize/DynArrayIndex/DynArraySetLength(need dynarray TypeInfo RTTI),IInterface/IEnumeratorbase interfaces,variantsunit,fglunit,TABconst. tint642 re-triaged: blocked by [[bug-pascal-record-cast-field-offset]], not RTL. - Runtime faults (P/A, investigate first): tforin3 + tstring1 segfault (139), tstring9 exit 2, tcase45_2/tcase46_2 exit 1, tarray11 exit 30, tover1 exit 1.
- Parser small holes: case-label edge cases (
case string label must not be empty,expected case label,case label must be constant),enumeratormodifier on class functions,for-inover custom enumerators, dynarray+concat (modeswitch arrayoperators), dynarray initializers,declared(NAME)conditional, operator overloading on plain types (LongInt is not a record or class),Selfin class methods, static-field access paths, ConstEvalPredin const-expr,Mismatch in MatchProcCall(internal error — investigate).
Method
Pick a sub-cluster, split it into its own narrowed ticket when starting real work; burn skip-list entries as they green.
