@ -0,0 +1,105 @@
This patches fixes an integer overflow in libiberty, which leads to
crashes in binutils. The long version of the objalloc_alloc macro
would have needed another conditional, so I removed that and replaced
it with a call to the actual implementation.
This has been compiled-tested only. We do not use this function in
GCC, therefore I want to commit this just to the trunk.

* objalloc.h (objalloc_alloc): Always use the simple definition of
the macro.

* objalloc.c (_objalloc_alloc): Add overflow check covering
alignment and CHUNK_HEADER_SIZE addition.
