Step D (hello.c + getauxval_fix.c) launches cleanly. E.minus-1 (hello.c + getauxval_fix.c + cpp_smoke.c) crashes. All three are plain-C trivial single-function files. Theory: the regression is triggered by having 3 or more cc::Build static libs in a Tauri Android cdylib, regardless of what the libs contain. Test: clone hello.c as hello2.c (same content, different symbol) and add a third cc::Build step compiling it. If this crashes, the trigger is just the number of static libs. If it launches, there's something magical about cpp_smoke.c specifically (unlikely — it was near-identical content). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
