I was careless in my initial report; I should have specified that I
tried rebuilding the *old* glibc and got a segfault. At this point,
all I really know is that building the eglibc 2.11.2-11 Debian source
package on my up-to-date sid amd64 machine fails:
make[3]: Entering directory `/home/steve/tmp/old-eglibc/eglibc-2.11.2/sunrpc'

Segmentation fault (core dumped)
The segfault is actually in the "ld-linux-x86-64.so.2" binary produced
during the build, not gcc as I had earlier written. The backtrace is:
(gdb) bt full

Hope this clarifies the issue somewhat.
