| Description | align_order_members() sorts a table's member list by a computed order key k and asserts k > 0 before inserting into the ordering list (src/compiler/semantics.c:1059). When the same member name is declared twice, the second declaration's key collapses to 0 and the assert(k > 0) aborts the compile. Duplicate members are a plausible user typo, not an exceptional input — the parser should emit a redefinition error, not crash.
Affected versions: flatcc v0.6.3
Severity: Medium (reachable assertion abort / SIGABRT; crash/DoS of the schema compiler)
