            Bug ID: 79232
           Summary: error: invalid rhs for gimple memory store
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

  Target Milestone: ---

Created attachment 40581
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=40581&action=edit
gzipped C++ source code

The attached C++ source code does this:

plyvel/_plyvel.cpp: In function ‘int __Pyx_SetItemInt_ByteArray_Fast(PyObject*, 
Py_ssize_t, unsigned char, int, int)’:
plyvel/_plyvel.cpp:19998:29: error: invalid rhs for gimple memory store

*iftmp.586;

I can see that this bug has been around since at least revision 242353,
dated 20161113.

I'll have a go at reducing the code.
