Perhaps the thread db isn't loading properly. gdb uses the thread db
library, or so I've heard, from glibc to help debug the program.
Unfortunately, I haven't been following eglibc and I'm not familiar with
how either loads the thread db library. But it sounds like there may be
a problem there. A wild guess -- perhaps a subtle difference in eglibc
is breaking its gdb support.
