WasmLinux: 放置でクラッシュする問題
okuokuどのくらい放置が必要なのかも今のところ判明していない。。
- VisualStudio版でしか見たことがない
- 常にwasm2c的な
FUNC_PROLOGUEでWASM_RT_TRAP_EXHAUSTIONする - backtrace的には
writeの内部。。？

このときのstack pointerは 0x4037fe80 、 trapは同様に WASM_RT_TRAP_EXHAUSTION 。
okuokuStack call depth countだな。。
変換後のソースには、
#if WASM_RT_USE_STACK_DEPTH_COUNT
#define FUNC_PROLOGUE \
if (++wasm_rt_call_stack_depth > WASM_RT_MAX_CALL_STACK_DEPTH) \
TRAP(EXHAUSTION); // ★ これでクラッシュしていると見られる
#define FUNC_EPILOGUE --wasm_rt_call_stack_depth
#else
#define FUNC_PROLOGUE
#define FUNC_EPILOGUE
#endif
これはWin32でのみ使われる。
wasm2cした関数からsetjmp/longjmpする際は、wasmのスタックポインタと同時にこのカウンタもsave/loadしてやる必要があると見られる。...これ確かにやってないな。。
okuokuとりあえずワークアラウンド
これはさっさとWasm exceptionの方に移動しないと不味いな。。
