kmk_sed is most probably using some undefined C behavior which only
fortunately worked with gcc-4.6.
and others gcc < 4.6
You should try compiling kmk_sed first with
-O0 and then checking whether the specific function having this problem there
is really valid ISO C.
don't understand whats help compile without optimization , which btw my
tests said that also doesn't work kbuild with -O0.
I checked the other email tip about kmk_sed, and conclusion kbuild
bundle a sed based on 4.1.5 but very modified.
As an illustration gcore also broke with gcc-4.7 but it was a bug of
gcore:
http://sourceware.org/ml/binutils/2011-12/msg00298.html
"as the code violates ISO C99 6.2.4 item 5 by using local variable
outside of
its block, GCC optimizes out the second memcpy, keeping there only that
memset."
well kmk_sed code not have necessary to be ISO C99, which could be a tip
try compile kbuild without change behavior of gcc < 4.7
or try to find what is not compatible , with some cflgs ...
The solution was patch sed file to not use or remove "GNU/POSIX
extensions to regular expressions" ...
UPDATE :
sed seems that stop work at all , nothing is replaced !
