[Guile-commits] 02/02: Handle zero-length bytevectors correctly in (system base types).

[Mark H. Weaver]

mhw pushed a commit to branch stable-2.0
in repository guile.

commit 2c032c221506841403fd3078641c3bf92535540c
Author: Mark H Weaver <address@hidden>
Date:   Thu Mar 26 23:13:47 2015 -0400

    Handle zero-length bytevectors correctly in (system base types).
    
    * module/system/base/types.scm (cell->object): Use 'get-bytevector-n'
      instead of 'get-bytevector-all', so that the zero-length case does not
      return EOF.
