ASAN can't deal with the coroutine stacks. In theory we can call into ASAN runtime to let it know about them, but ASAN still has problems with fork or exit happening from a non-system stack. Bypass all possible problems by just having a full OS thread for each libthread thread. The threads are still cooperatively scheduled within a proc (in thos mode, a group of OS threads). Setting the environment variable LIBTHREAD=pthreadperthread will enable the pthreadperthread mode, as will building with CC9FLAGS='-fsanitize=address' in $PLAN9/config. This solution is much more general than ASAN - for example if you are trying to find all the thread stacks in a reproducible crash you can use pthreadperthread mode with any debugger that knows only about OS threads.
This is a port of many Plan 9 libraries and programs to Unix.
Installation
To install, run ./INSTALL. It builds mk and then uses mk to run the rest of the installation.
For more details, see install(1), at install.txt in this directory and at https://9fans.github.io/plan9port/man/man1/install.html.
Documentation
See https://9fans.github.io/plan9port/man/ for more documentation. (Documentation is also in this tree, but you need to run a successful install first. After that, "9 man 1 intro".)
Intro(1) contains a list of man pages that describe new features or differences from Plan 9.
