It *is* surprising given that the testcase does have declarations of abort() or rand() -- which are the only two external functions referenced. > > The following patch adds <stdlib.h> to the test. I don't think this a correct fix. [In most such cases the real problem can be found out by examining why linking a test against glibc works, but against bionic -- doesn't.] How are you linking this testcase? Please post both the link line from testsuite log and verbose output of linking (obtainable by adding "-v" to the link line). Thank you, -- Maxim Kuvyrkov www.kugelworks.com
