This failure will happen generally w/ all gnu apps if you built uclibc w/ 
GLIBC_COMPAT_MALLOC enabled and built your apps, then disable the option 
and rebuild uclibc. There is no real life solution for it, the gnulib ppl 
consider the glibc malloc implementation as ok. Although it is not quite 
correct, current apps go the glibc way so best you can do is keep that 
compat option enabled

gnulib devs decided that if malloc is not compat, then also regex has to 
be used from gnulib (regex bacame a requirement for the malloc module)
(regex is what fails in sed, and will in many gnu apps)
