On noMMU platforms, the following code gets compiled:
child_stack = xmalloc (STACK_SIZE * 4);
Where child_stack is a gdb_byte*, and xmalloc() returns a void*. While
the lack of cast is valid in C, it is not in C++, causing the
following build failure:
../nat/linux-ptrace.c: In function 'int
linux_fork_to_function(gdb_byte*, int (*)(void*))':
../nat/linux-ptrace.c:273:29: error: invalid conversion from 'void*'
to 'gdb_byte* {aka unsigned char*}' [-fpermissive]
child_stack = xmalloc (STACK_SIZE * 4);
Therefore, this commit adds the appropriate cast.
gdb/ChangeLog:
* nat/linux-ptrace.c (linux_fork_to_function): fix cast to
gdb_byte*, needed for C++ build.
