Description:   Opened: 2008-07-05 12:09 0000 
!!! The issue is valid only for toolchains compiling packages with
-D_FORTIFY_SOURCE=2. !!!

The problem is caused by the use of vasnprintf. It would use a user supplied
format string "%n". FORTIFY_SOURCE blocks the attempt causing a crash. The
vasnprintf was taken from gnulib. Upstream suggested a workaround which
alsready included in sys-devel/m4.
Other solutions:
- Mandriva prevents cvs from compiling with -D_FORTIFY_SOURCE=2
- FC8 and FC9 uses and older version of cvs (1.11.22)

vasnprintf modifications just like in m4

Based on the suggestions of gnulib developers. May cause loss of functionality.
Works for me.

Modified ebuild using the above patch

Needed until cvs will merge the gnulib changes from upstreams.
