Description Timo Lindfors 2005-05-30 18:31:36 UTC

Description of problem:
dos2unix crashes with some specific command line parameters.

Version-Release number of selected component (if applicable):
dos2unix 3.1 (Thu Nov 19 1998)
linux 2.6.11-1.14_FC3

How reproducible:
Always

Steps to Reproduce:
1. mkdir -p video/video/natural/microsoft-2.3-001213/sys/decoder/ mpeg4ip-1.2/common/video/mpeg4-2000/sys/decoder/
2. touch video/video/natural/microsoft-2.3-001213/sys/decoder/mbinterlacedec.cpp mpeg4ip-1.2/common/video/mpeg4-2000/sys/decoder/mbinterlacedec.cpp
3. dos2unix video/video/natural/microsoft-2.3-001213/sys/decoder/mbinterlacedec.cpp mpeg4ip-1.2/common/video/mpeg4-2000/sys/decoder/mbinterlacedec.cpp
  
Actual results:
dos2unix: converting file video/video/natural/microsoft-2.3-001213/sys/decoder/mbinterlacedec.cpp to UNIX format ...
dos2unix: converting file mpeg4ip-1.2/common/video/mpeg4-2000/sys/decoder/mbinterlacedec.cpp to UNIX format ...
*** glibc detected *** malloc(): memory corruption: 0x09f17060 ***
Aborted (core dumped)


Expected results:
dos2unix should recrate the files (they are empty so there isn't much to convert) and not crash.


Additional info:
This bug seems to be very sensitive to the length of the filenames that are given as command line arguments.

Comment 1 Sitsofe Wheeler 2005-05-30 18:47:43 UTC

Sounds like a dup of bug #150277

Comment 2 Tim Waugh 2005-05-31 12:02:50 UTC

Perhaps time for an update.

Comment 3 Tim Waugh 2005-05-31 14:58:42 UTC

Please try this update:

Comment 4 Max Kanat-Alexander 2005-06-29 03:25:08 UTC

I get something similar on RHEL 4, when trying to rebuild an old Red Hat
perl-5.8.0 SRPM (so that I can have multiple perls on a development testing
machine):

dos2unix: converting file jpl/JNI/JNI.xs to UNIX format ...
*** glibc detected *** free(): invalid pointer: 0x08792038 ***
/var/tmp/rpm-tmp.99171: line 74: 24303 Aborted

I can re-arrange the dos2unix calls in the perl.spec file, and then I get:

dos2unix: problems renaming 'jpl/JNI/d2utmpvSaZCV' to 'jpl/JNI/JNI.xs'
          output file remains in 'jpl/JNI/d2utmpvSaZCV'

Comment 5 Max Kanat-Alexander 2005-06-29 03:25:55 UTC

Oh, and FWIW, I have dos2unix-3.1-21.

Comment 6 Max Kanat-Alexander 2005-06-29 03:31:16 UTC

OK, I can confirm that at least my problem is fixed by dos2unix-3.1-24.

Comment 7 Tim Waugh 2005-06-29 08:16:13 UTC

Will someone try the test update for Fedora Core 3 mentioned in comment #3? 
Otherwise there is no point in releasing it as a final update.
