Scala 2 compiler does not crash. |

It looks like it depends on the code. object Main {
def main(args: Array[String]): Unit = {
println(s"""aaa \s bbb""")
}
}But it fails with this code: object Main extends App {
println(s"""aaa \s bbb""")
}Also, JFTR with scala compiler 2.12.19 and 2.11.12 don't produce any error.

@unkarjedy you have other actors to blame in your stack I think this is why it's important to keep a "plain scalac" tool. I'm using sdkman currently, and if scala-cli supplants it in that role, then various simple bugs may be due to "other tooling". This is not contingent on any particular tool; anything adjacent to scalac adds points of failure. The bug or impedance mismatch could be anywhere. I can attest that just the plain REPL introduces distortions. Edit: I was actually thinking of scala-cli supplanting scala runner. In this case, I wonder what magic is performed on |

Also wish to voice my support for |
In practice, frequently when I say "in Scala X" or "scala compiler", I don't mean
I should have mentioned that I got the same results in SBT terminal. Also, it turns out it's specific to class Main {
s"""aaa \s bbb"""
}Also Notice error Interestingly, when not using Also, if you replace UPD So turns out the main difference in the example with the If you use compiler-based highlighting, you can see in the editor that a wrong range is reported: |

Sorry to comment further instead of on a scala 2 ticket, but another clue is that it doesn't happen under Bloop wasn't starting for me with scala-cli 1.1.3, but I fetched 1.2.1 and could reproduce your issue with I joked once that we no sooner got rid of |
In the end, even though plain scalac doesn't crash itself, it's still the one to blame as it seems. |

That might be appropriate for a Spree? |
Java multiline blocks supports

Given that
\sis not reserved, the compiler could support by simply replacing with\sAt first glance, this should be trivial to fix.
This wouldn't work in non-interpolated multiline string literals and in raw string literals because they don't support escape sequences.
Still, it could still be a nice addition.
