Hi,
I have a repeatable crash in udev when it tries to detect my swap
partition (and maybe in other cases that I didn't had the time to
investigate more)
With the udev-132 on frugalware, I get the following backtrace, when I:
udevadm test /block/hda/hda2
I get the following stack trace:
#0 0x08054150 in util_strlcat ()
#1 0x0804a8aa in udev_event_apply_format ()
#2 0x0804e2c6 in udev_rules_apply_to_event ()
#3 0x080497ae in udev_event_execute_rules ()
#4 0x0805b704 in udevadm_test ()
#5 0x08059b83 in run_command ()
#6 0x08059e24 in main ()
or in valgrind

So it means a null pointer is used somewhere. Infortunatly I was not
able to produce the line numbers of the errors.
If needed I can try to investigate more with some indications.
Cheers,
Michel
