Implemented. OK to check-in?
This is a regression since gdb-7.1.
Testfile tested on x86_64-fedora13-linux-gnu.
While the malloc() result gets ignored warning gets generated only with
_FORTIFY_SOURCE level > 0 so we probably do not have to care about in the gdb
testsuite.

* gdb.base/charset-malloc.c: New file.
* gdb.base/charset.c (malloc_stub): New prototype.
(main): Call it instead of malloc itself.
* gdb.base/charset.exp: Use only prepare_for_testing.
(binfile): Remove the variable.
