On Kubuntu 9.04 amd64 "Jaunty" after executing path/to/gdb/configure then make,
I get:

The offending line is
fgets (buffer, sizeof (buffer), procfile);
(Before you tell me to use the Ubuntu gdb package: the reason I'm building gdb
myself is to try to avoid gdb crashes in iterate_over_threads , possibly because
Ubuntu should have repackaged gdb for kernel and/or libc updates --
