Looks like “Bad number” is a different kind of error than other
syntax errors.  If, say, lone ¯ is evaluated in ⎕EC¨ last then
it seems to abort the whole line ⎕EC¨ appears in.
I'm at r712.

      ⎕EC¨'1¯'  ⍝ no result at all
      ⎕FX'f x' '⊣ ⎕EC¨x'
      f'1¯'  ⍝ unexpected output
  1  0 0  1    0  2 2  SYNTAX ERROR

When it comes first, the interpreter does a double free somewhere
and gets aborted:

*** Error in `/usr/bin/apl': free(): invalid pointer: 0x00007ffd734c2b50 ***
