Tried to redo this error using make bpy. Although I got a different error with jemalloc.

Thanks for the report, but we do not accept reports related on compilation errors and only accepting reports happening with official blender builds. All the rest is to be handled via mailing list or the IRC room. See the bug report guidelines for details.
