i've a working gnueabihf system and it seems to be enough stable.

I experimented these issues:

file-5.07 output

root@efikamx:/mnt/DEVEL# file mio
mio: DOS-executable (
root@efikamx:/mnt/DEVEL# md5sum mio
ba52d7e6f0c41a7bcaf49a216864e34a mio

instead it should be..

acrux@killer:~$ file mio
mio: Linux rev 1.0 ext2 filesystem data
acrux@killer:~$ md5sum mio
ba52d7e6f0c41a7bcaf49a216864e34a mio


and also alsa-utils segfaults.
Are there similar experiences? Patches available?

No idea how/why this is happening, but I would suggest looking at the debian gcc-4.{4,5,6} and binutils packages, as well as the eglibc one, and checking for patches relevant to linaro/hardfloat patches.

Haven't seen those errors at all, to be honest, I do get the occasional segfaults, but only during compilation.

just now noticed the same wrong file-5.07's output on PowerPC for this specific file type. Well, i'm obliged to investigate and/or bug report.

About alsa-utils segfault i'm still in trouble.
Anyway, thanks for your suggestion. I'll take a look for debian sources.

this fixed my issue (on PowerPC too).
root@efikamx:/usr/ports/arm/core/file# file /mnt/DEVEL/mio
