Known Problems

1. System linker /usr/bin/ld (called by gcc's collect2) crashes when linking C++ thorns if GNU ar is used to create the libraries.

   If GNU ar is used to create libraries containing C++ thorns (note that Cactus builds a library for each thorn) then the system linker /usr/bin/ld crashes when it is called by gcc's collect2.

   The workaround is to use the system's ar if you have any C++ thorns.
