weaselbot	9a2c64d31c	Fix broken endInsertionPoint forwarding chain resolution in DEBUG_VERBOSE print In the Phase 2 debug block of ConflictSet::Impl::interleavedWrites, the loop resolving the end insertion point's releaseDeferred/forwardTo chain followed the begin node's chain instead (e = b->forwardTo). Once b is resolved, b->forwardTo aliases the Entry union member, so e was assigned garbage derived from version bytes and the loop dereferenced it, causing a SEGV or hang whenever DEBUG_VERBOSE builds traced writes. Use the end node's own forwarding chain (e = e->forwardTo), matching the production code in the same loop body and in Phase 3.	2026-08-30 20:17:22 -04:00

weaselbot	8c55e835c4	Fix NEON type mismatch in conflictMask16 for gcc/aarch64 + USE_64_BIT=1 vcgtq_s64 returns uint64x2_t but vmovn_s64 requires int64x2_t. clang accepts the implicit conversion via lax vector conversions, but gcc does not. Add an explicit vreinterpretq_s64_u64 so the code compiles with gcc on aarch64 when USE_64_BIT=1. This path is otherwise untested in CI (aarch64 matrices use USE_64_BIT=0; the 64-bit-versions matrix uses amd64 AVX compare16). Closes #80	2026-08-16 21:16:23 -04:00
