There is missing prototype for "char * getfoo();" in test.c.
When added, the first test also passes.

Well, next question would be why the second case passes
even without prototype ...

The difference between 1st and 2nd testcase is location of buf.
In the second case,  it is in main program,
it is mapped bellow 2GB mark - i.e. 0x5009e0.
In the first case, it is in shared library,
it is mapped above 2GB mark - i.e. 0x2aaaaacc1ca0.
