Can't compile a filename containing "-" character in OCaml 4.11 on AMD64 #9461
Description
perl4caml contains an old test which is literally called 001-start.ml. This fails to compile on x86-64 only with the new compiler:
ocamlopt -w s -I wrappers -c test/001-start.ml
File "test/001-start.ml", line 1:
Warning 24: bad source file name: "001-start" is not a valid module name.
/tmp/camlasm8c525e.s: Assembler messages:
/tmp/camlasm8c525e.s:59: Error: expected comma after name `caml001' in .size directive
File "test/001-start.ml", line 1:
Error: Assembler error, input left in file /tmp/camlasm8c525e.s
While we should obviously rename the test, this appears to be an unintentional regression.
