Description

I see a glibc running the org.apache.harmony.luni.tests.java.lang.RuntimeTest on Ubuntu 10.04:

• • • glibc detected *** /federatedBuild/target/hdk/jdk/jre/bin/java: munmap_chunk(): invalid pointer: 0x00feb3de ***

The problem is occurring when freeing a string array, which is being initialised using:
char *newArgv[lenargv+2];
newArgv[lenargv+1] = (char *)0;
the free throws a glibc when freeing the null string in the array.
