Nim
## This test runs the fixture in a child process. The fixture calls `abi = c`
|
|
## entry points from threads that the Nim runtime does not know. A regression
|
|
## crashes the child, not this suite. The child uses the same --mm switch as
|
|
## this run. The regression is fatal under refc and harmless under orc.
