i noticed that readline-2.2-4 makes gdb-4.17.0.11-6 dump core -- only debug info i could get was that the actual segfault was in _IO_fflush (iofflush.c:41). there may be other things it crashes.. suggest a minimum version for readline be added, as readline-2.2.1-5 fixes it. (sure is nice to have gdb back :) )
This is a glibc shared library problem. You cannot mix glibc-2.0.x shared libraries with glibc-2.1 shared libraries because of structure changes in libio (e.g. _IO_fflush). Recompile the old readline.
