I'm using the standard install of 2.0.7 to compile busybox under 
Debian Slink, and LRP 2.9.7 (Oxygen) with the security-fixed 2.0.7.

Here is the ltrace you asked for:

--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++

By the way, the command "strip charconv" also generates the same 
error in the same system call ("lseek(4, 0, SET_SEEK)").

I'm wading through the swamp here..... I expect I'll learn something 
(especially of strace and ltrace) but OHHHHH what a stench :-) I'm 
SURE I made a mess of things SOMEWHERE....
