Just to clarify before anyone is getting confused: This is most surely
not a general issue with LilyPond but with the module loading code in
the "scholarly" package. "input-file" here is a list split from the
(*location*) string.
Then the last two elements of that list are retrieved, and for some
reason the location list here doesn't have enough elements.

Please insert the line
(dummy (ly:message "\n\n\ninput-file: ~a\n\n\n" input-file))

between the lines starting with "(input-file" and "(ctx" in module.ily
(around line 77) and tell me what the output is (presumably immediately
before the crash). Maybe give the output of a failing and a crashing
compilation.
