segmentation fault

hi,

yesterday I tried to build a target in trunk. I interupted the build during 
glibc, made a svn up and started the build-target again. The script failed at 
the first packages gzip ( New Revision: 22950) with some errors 
like "gzip.texi:83: Unknown command 'abbr' " and "gzip.texi:84: Misplaced 
{ " .
OK, I thougt the interrupted build of glibc was evil and did a 

./scripts/Build-Pkg -cfg yky-matchbox glibc

to build a correct glibc.

After a short while there was a "Speicherzugriffsfehler" / Signal 11 /   
segmentation fault

Well, not only the build of the package is broken, the whole host-system is 
broken (t2-minimal 6.0.1), too. Also a chroot from a live-cd is not possible, 
again a segfault.

Is it a known problem?
