Closed jbajwa closed 8 years ago

Failing with following error:

In file included from .././src/heap/store-buffer.h:12:0,
                 from .././src/heap/heap.h:21,
                 from ../src/heap/heap.cc:5:

cc1plus: all warnings being treated as errors

on GCC 4.8.4 or earlier it builds cleanly. Seems to be a known gcc bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59124
