Bug 366607 – sys-fs/squashfs-tools - segfaults when built with USE=-gzip

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description avx 2011-05-09 15:26:44 UTC]

On ~amd64, gentoo-sources-2.6.38-r4, squashfs-tools-4.2, mksquashfs segfaults when built with USE=-gzip. Neither does it pick up nor does it list other compressors (xz, lzo) when built with USE="-gzip lzma lzo". Support for all named options is built into the kernel.

Reproducible: Always

Steps to Reproduce:
1. USE="-gzip lzma lzo xattr" squashfs-tools
2. mksquashfs file file.sqf (using "-comp {xz,lzo} doesn't work either)
3.
Actual Results:  
Segfault when the read buffer is full

Expected Results:  
should squash the dir/file

Full confirm for me...

OK, mksquashfs -comp lists /no/ compression types when USE=-gzip, and indeed fails in several ways when USE=-gzip, so I am going to remove the USE flag and make it always build gzip support.

Oh, I guess you didn't see the einfo:
  "You can set the default compression (gzip, xz or lzo) by exporting SQUASH_FS_DEFAULT_COMP"

I've tried it and it doesn't seem to work.

Fixed in 4.2, which is going stable in bug #400937. IUSE=gzip has been removed until upstream actually supports this properly.
