Steps to reproduce:
Enter org mode (I am on cc2490a7061955395c4f5a1a23a088044554a2f7)
Type *bold* *bold* *bold*
Notice that the second instance is not bolded while the first and third
are.

This doesn't occur if there is normal text between the text with
emphasis markers. It shows for all of /italics/, *bold*, _underline_,
and +strikethrough+
