In the platform-specific implementations of linker_md.c, we see the dll_build_name methods begin with a call to jvmtiAllocate.
We then appear to rush ahead and try to use that variable without checking for a null. I propose moving the null check to the point *before* we try to use that variable, to avoid any possible SEGV.
