Fix '-data-read-memory-bytes' typo/assertiongdb-7.10-branch
Backported to the 7.10 branch per this thread: https://www.sourceware.org/ml/gdb-patches/2016-02/msg00134.html This patch fixes a typo in target.c:read_memory_robust, where it calls read_whatever_is_readable with the function arguments in the wrong order. Depending on the address being read, it can cause an xmalloc with a huge size, resulting in an assertion failure, or just read something other than what was requested. The problem only arises when GDB is handling an MI "-data-read-memory-bytes" request and the initial target_read returns an error status. Note that read_memory_robust is only called from the MI code. gdb/ChangeLog: * gdb/target.c (read_memory_robust): Call read_whatever_is_readable with arguments in the correct order.
