I've already opened a PR for this issue, but wanted to open an issue for documenting purposes.
Copy-pasta from the PR description:
I have a Swift CLI that utilizes ShellOut to interact with binary executables. When I use shellOut too many times, I sometimes hit an exception that looks something like:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Failed to set posix_spawn_file_actions for fd -1 at index 0 with errno 9'
*** First throw call stack:
(
0 CoreFoundation 0x00000001859672ec __exceptionPreprocess + 176
1 libobjc.A.dylib 0x000000018544e788 objc_exception_throw + 60
2 Foundation 0x0000000186a92eb4 -[NSConcreteTask launchWithDictionary:error:] + 4240
I've been able to determine this is due to the Pipe objects from ShellOut not being closed properly.

swift
command runs long enough, you'll hit an exception like the above.The text was updated successfully, but these errors were encountered:
