thanks David and kyak I just did the fast way. remove the readline.so when first boot: committed at: http://qi-hw.com/p/openwrt-packages/0df4b6d

Crash happens in libreadline. It jumps to address 0 after loading the branch target out of the plt ('lw t9,...(gp)'). This looks very much like an unresolved symbol in libreadline, where the dynamic linker just left a 0-pointer. Libreadline is loaded dynamically via /usr/lib/python2.6/lib-dynload/readline.so . When that readline.so does a dlopen() with lazy symbol resolving, then 0-pointers on unresolved symbols would be quite natural. Looking at the libraries that where loaded at the time of the crash, I can see that libncursesw.so.5 is loaded, but libncurses.so.5 (without 'w') is not. I think this is needed by libreadline. Looks like thelibncursesw stands for the "wide" version of ncurses, i.e., supporting two-byte characters. It doesn't need to have "regular" version of ncurses loaded because the "wide" version is backwards compatible with the "regular" one (http://invisible-island.net/ncurses/ncurses.faq.html, "The ncurses and ncursesw libraries are reasonably source-compatible. That is, an application written for "ncurses" will build with "ncursesw"."). I just want to clarify that it doesn't have anything to do with the letter "w" :) David, you did a great find. So I searched for keywords and here's what i found: http://lists.busybox.net/pipermail/uclibc/2011-March/045081.html It started here: http://lists.busybox.net/pipermail/uclibc/2011-March/045051.html (there are other related discussions for dynamic linker, python, readline and ncurses if you search their mailing lists :) So at the end, seems that the readline needs to be patched for that. David, if you're going to do that (http://lists.busybox.net/pipermail/uclibc/2011-March/045079.html), please force the link to wide ncurses, so one would be able to type wide-char in python command line :)
