OSError errorCode is always 0

Looks like a bug. nim-#devel/lib/pure/osproc.nim:1123, It works properly after being modified to the following. code var error: cint let sizeRead = read(data.pErrorPipe[readIdx], addr error, sizeof(error)) if sizeRead == sizeof(error): raiseOSError(OSErrorCode(error),

tag effects differ

Thank you very much for your reply. allocChunk is an approach that enables users to customize their own allocator types. Regarding the issue with RootEffect, I solved it using a hack way, maybe this is a case of error, but it did solve my problem and no exceptions appeared in the tests.

How to make custom linear containers automatically converted to OpenArray, like SEQ or Array

Sorry, this solution seems to have a strong side effect, it generates c code that calls autoToOpenArray twice. I can observe this phenomenon when I insert the echo statement in it. Reproducible example: type Slice*[T] = object firs
