WORKAROUNDS
===========
Hope this helps in debugging. See
http://forum.dlang.org/post/n4rbeh$2eir$1@digitalmars.com
1) Changing the order of the members of xlmref seems to be a workaround:
struct xlmref
{
xlref reflist;
ushort count;
}
2) Changing the 2x ubyte to ubyte[2] seems to be a workaround:
struct xlref
{
ushort rwFirst;
ushort rwLast;
ubyte[2] cols;
}
