## Docs
@ -85,4 +87,10 @@ Important cli options:
1. `--track-origins=<yes|no> [default: no]`, Controls whether Memcheck tracks the origin of uninitialised values. By default, it does not, which means that although it can tell you that an uninitialised value is being used in a dangerous way, it cannot tell you where the uninitialised value came from. This often makes it difficult to track down the root problem.
1. `--show-reachable=<yes|no> , --show-possibly-lost=<yes|no>`, to show the using memory.
## Analysis
1. About setjmp and longjmp, read [setjmp](https://gitee.com/winlinvip/srs-wiki/raw/master/images/st-setjmp.jpg).
1. About the stack structure, read [stack](https://gitee.com/winlinvip/srs-wiki/raw/master/images/st-stack.jpg)
1. About asm code comments, read [#91d530e](https://github.com/ossrs/state-threads/commit/91d530e#diff-ed9428b14ff6afda0e9ab04cc91d4445R25).
