No stack trace is printed when a proc in os/syncio module throw an exception at compile time #22558

Open demotomohiro opened 1 year ago

demotomohiro commented 1 year ago

Description

When procedures in os/syncio module failed and throw an exception at compile time, it doesn't print stack trace. So it is hard to find which procedure threw the exception.

For example: testvm.nim

static:
  writeFile("/nopermission", "")

A potential solution is to catch the exception in the vmops and use stacktrace like what is said in the https://github.com/timotheecour/Nim/issues/363 and https://github.com/nim-lang/Nim/pull/11955
