bug#15765: Crash in directory_files_internal |
Date: |
Wed, 30 Oct 2013 18:06:39 -0400 |
This crash occurred after eval'ing the expression
(directory-files "~/Library/Logs/DiagnosticReports" t "Aquamacs.*.crash")
This directory exists, contains a few files, and I had eval'ed that just a few
second earlier without problems.
The bug does not reproduce.
Relevant lines in my dired.c:
> 267 Lisp_Object fullname;
> 268 ptrdiff_t nbytes = len + directory_nbytes + needsep;
> 269 ptrdiff_t nchars;
>
> 271 fullname = make_uninit_multibyte_string (nbytes, nbytes);
> 272 memcpy (SDATA (fullname), SDATA (directory),
> directory_nbytes);
>
Full crash log below. The running binary was built based on Emacs head as per
Oct 24, git refid 7c5015698c3, with some patches, but none to dired.c.
