Thread var cannot be returned from a proc. Causing SIGSEV

[Alogani]

Description

Hello,

Apparently, it is not possible to create a thread var and return it from a proc. It causes a SIGSEV

import os

proc threadMain() {.thread.} =
    sleep(100000)

proc main(): Thread[void] =
    var th: Thread[void]
    createThread(th, threadMain)
    return th

var th = main()
joinThread(th)

Nim Version

nim v2.0.4 on Fedora

Current Output

No stack traceback available
SIGSEGV: Illegal storage access. (Attempt to read from nil?)

Same behaviour from 1.0 to devel, with ORC and refc.

[metagn]

Likely related is #24094. The thread address is not supposed to escape during the thread's lifetime. I'm not sure if this is supported but you can do something like:

import os

proc threadMain() {.thread.} =
    sleep(1000)

proc main(): ref Thread[void] =
    new(result)
    createThread(result[], threadMain)

var th = main()
joinThread(th[])
echo "abc"
