Package: cfs
Version: 1.4.1-16
Severity: important
Well, after a couple months, a couple days ago I just updated
the whole system. Still trying to understand which is the cause,
but when writing 'some files' cfsd crashes with a SIGSEGV
and leaves my directory unusable.
I've been using cfsd for years now, and I don't believe the
directory to be corrupted. The application causing the problem
is probably procmail.
By recompiling with nostrip,noopt, I get the following gdb backtrace:
Program received signal SIGSEGV, Segmentation fault.
