csup in repomirror mode dumps core @ stable/8

[Dmitry Morozovsky]

Dear colleagues,

some 2 days ago my repo mirror (stable/8 at amd64) starts dumping core on copying 
repo:

...
 SetAttrs CVSROOT-src/Emptydir
 Edit CVSROOT-src/access,v
Segmentation fault (core dumped)

deleting files from sup/cvsroot-all/ did not help

unfortunately, quick usual `make -DDEBUG_FLAGS=-g' in /usr/src/usr.bin/csup 
does not work, and I did not dig into this deeply yet, so trace are without 
parameters:

(gdb) bt
#0  0x0000000000410676 in rcsdelta_addlog ()
#1  0x0000000000412b15 in rcsparse_run ()
#2  0x0000000000412453 in rcsfile_frompath ()
#3  0x0000000000417c45 in updater_rcsedit ()
#4  0x0000000000419a59 in updater_batch ()
#5  0x000000000041a1d1 in updater ()
#6  0x00000000004158c4 in thread_start ()
#7  0x0000000800a1c511 in pthread_getprio () from /lib/libthr.so.3
#8  0x0000000000000000 in ?? ()
Cannot access memory at address 0x7fffff1fa000

Any hints?
