#define  foo foo
#define  bar foo
bar
Add test and fix bug leading to infinite recursion. The test case here is simply "#define foo foo" and "#define bar foo" and then attempting to expand "bar". Previously, our termination condition for the recursion was overly simple---just looking for the single identifier that began the expansion. We now fix this to maintain a stack of identifiers and terminate when any one of them occurs in the replacement list. 2010-05-17 10:15:23 -07:00			`#define foo foo`
