Crashes here too. Goody! That means it should actually be possible to
find and fix it fairly easily. But we probably need to plan for a
0.61.3 release.

Hmm. I think I've heard that one before. Personally, I'm staying on
libc5 until they've hashed out most of the libc6 problems, so I can't
debug it. It sounds a bit like the old BSD/SYSV difference where the
latter had one-shot signal handlers that had to "recharge" themselves
every time. 

However, all the 
	setjmp(R_Toplevel.cjmpbuf);
seem to be properly followed by
	signal(SIGINT, onintr);

The RedHat website contain references to a rather large number of
glibc fixes. The last one says:

(01-Apr-1998) New glibc packages are available now on the ftp site.
These new packages fix (finally!) the problems in the dynamic loader
code. Applications compiled for glibc using a lot of shared objects
should now work reliably under glibc. Also various fixes to the
sigprocmask handlers are in place.

Anyone checked this with Debian-pre2.0?
