Very likely a problem with putting .ctors into .init_array (top of .0.3
ChangeLogs have HJ's patch to do that). To debug, I'd first look at
DT_INIT_ARRAY and DT_INIT_ARRAY_SZ (readelf -d on the bad libc) to see if they
make sense, ie. match the .init_array sections (readelf -S). Next I'd dump out
.init_array (objdump -s -j .init_array) to see whether it did in fact have a -1
pointer. If so, build the library again asking for a linker map file so you
can tell where the -1 comes from.
