Bug#658132: libgcc1: installation fails with "FATAL: cannot determine kernel version"

[Paulo Zanoni <przanoni@gmail.com>]

Package: libgcc1
Version: 1:4.6.2-12
Severity: normal

Dear Maintainer,

I'm not sure if this is a libgcc bug: maybe it is something inside dpkg that is
failing. Feel free to reassign the bug.

I use a kernel generated with the following command:

time fakeroot make-kpkg -j4 --append-to-version $(date +%Y%m%d%H%M) --initrd
kernel_image kernel_headers

Now I'm failing to install packages:

The important lines seem to be:

Segmentation fault

This has already happened to me yesterday. I had to reboot to one of the
"debian" packaged kernels and then I could fix the problem. Maybe the script
that parses the kernel version can't recognize 3.2.0201201301744+ as a correct
version? It shouldn't segfault... Either we fix the script or we change make-
kpkg's append-to-version argument to not allow strings that our scripts won't
recognize.

I'm using Debian Testing.

Thank you,
Paulo
