Segfault on Racket v6.2

[bennn]

This program causes a segfault for me on Racket v6.2. Any idea what's happening here?

#lang racket/base

(module+ siggy
  (require (only-in math/matrix vector*->matrix))
  (vector*->matrix '#()))

Here's my segfault

SIGSEGV MAPERR si_code 1 fault on addr 0x7ffed7232d98
zsh: abort (core dumped)  raco6.2 make foo.rkt

Maybe something submodule or Typed Racket - related?

Without the module+ I get the correct error:

vector_->matrix: contract violation
expected: nested vectors with rectangular shape and at least one matrix
element
given: '#()
context...:

What does it do on head?

[samth]

To answer my own question, it works correctly on HEAD.

[bennn]

Yes, head and Racket 6.1 work fine for me.

The only-in is also necessary! But I'm not sure if another function besides vector*->matrix could trigger the bug.

[samth]

Is there a reason not to close this?

[bennn]

No, there's not strong reason to keep this open.

But I would really like to know what happened, and whether the source of the problem is covered by a regression test.

[samth]

I'm closing this -- feel free to use git bisect to try to find what happened.
