[Bug 38964] New: utils.c NULL pointer reference in memcpy

https://bugs.winehq.org/show_bug.cgi?id=38964

Bug ID: 38964
           Summary: utils.c NULL pointer reference in memcpy
           Product: Wine
           Version: 1.7.47
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: tools
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

In widl/utils.c:379
memcpy( output_buffer + output_buffer_pos, data, size );
the pointer data is NULL. 
This is during wine build on x86-64 with default -m32 option.
I double checked it by prefixing the instruction with "assert(data)" as in
assert(data),memcpy( output_buffer + output_buffer_pos, data, size );
