Also thttpclient_ssl.nim(171) thttpclient_ssl does not appear to be a real line. thttpclient_ssl.nim is only 131 lines?

timotheecour commented 3 years ago

@treeform given fact that https://github.com/nim-lang/Nim/pull/16220 is green for ssl tests, there may be some (maybe indirect) link between your PR and that test failing after all

does not appear to be a real line. thttpclient_ssl.nim is only 131 lines?

that's strange; can happen with {.line.} pragma but not case here; might be some interaction with include or template, but still unclear, we should reduce / file a bug (if you can !)
