调研方向

Start with tests/test_lsp_asan.sh and its make lsp CFLAGS=... steps, then inspect how src/eigenlsp is selected and rebuilt. Reproduce with a stale release binary newer than its sources, and use nm or ldd to verify the executed binary is instrumented. Done means the harness fails on the stale release case and leaves src/eigenlsp as a release build or never modifies it.

描述

area:gates kind:gate-defect

Found by the builder on #1364.

tests/test_lsp_asan.sh builds with make lsp CFLAGS=.... CFLAGS is not a make dependency, so when src/eigenlsp is newer than its sources, nothing is rebuilt. The "ASan" run then exercises the RELEASE binary and prints green. Its closing "rebuild normal" step is a no-op after a real ASan build, so it leaves the 29 MB instrumented binary in place of the release one. Both happened on 2026-09-28.

Done when

  • The harness builds the ASan eigenlsp into its own output path (or forces the rebuild), and fails unless the binary it runs is instrumented. For example, check for __asan_init in nm output, or for the ASan runtime in ldd.
  • Planted once: a stale release src/eigenlsp newer than the sources makes the harness red, not green.
  • After the harness finishes, src/eigenlsp is the release build again (or the harness never touches it).
