Hi there!
I managed to let udev-131 segfault at startup.
I configured it like this:
CFLAGS="-Wall -ggdb" ./configure --prefix=/usr --sysconfdir=/etc --exec-prefix=
Running it in gdb shows it segfaults at udev-rules.c:831
(gdb) run
Starting program: /tmp/udev-131/udev/udevd
Program received signal SIGSEGV, Segmentation fault.
0x0804ea06 in get_key (udev=0x9175008, line=0xafcdc8f0, key=0xafcdc5d8,

at udev-rules.c:831
831 dbg(udev, "%s '%s'-'%s'\n", operation_str[*op], *key, *value);
Longer backtrace:

This is the rules file it seems to parse at that moment:
# Created by /lib/udev/write_root_link_rule
# This rule should create /dev/root as link to real root device.
