Hi Yuriy,
OK, that all makes sense.
Here's the full trace with symbols:
#8 0x8017f167 in path_compare (a=<optimized out>, b=0x0) at
../src/basic/path-util.c:390
d = <optimized out>
__PRETTY_FUNCTION__ = "path_compare"
so, it assert() as `b == NULL`
#9 0x8017f308 in path_equal () at ../src/basic/path-util.c:433
No locals.
#10 0x8010c661 in device_setup_unit (m=m@entry=0x81f377f8, dev=dev@entry=0x0,
path=path@entry=0x82005aa8 "/dev/sde1", main=false) at ../src/core/device.c:324
e = 0x82006760 "dev-sde1.device"
sysfs = <optimized out>
u = 0x8200bad0
delete = <optimized out>
r = <optimized out>
__PRETTY_FUNCTION__ = "device_setup_unit"
__func__ = "device_setup_unit"
and here argument `b` is sysfs, so sysfs was NULL;
and it is NULL as dev was NULL.

__PRETTY_FUNCTION__ = "device_found_node"
__func__ = "device_found_node"
and here dev could be NULL only if stat() returned error, and that error
was ENOENT (see line 822).
Regression by commit v228-745-gac9d396. Before that commit,
device_setup_unit checked that sysfs is not NULL before calling
path_equals().
I'd guess this commit should be just reverted.
