Latent bugs have been a very common source of run-time problems, 
whether for native apps or for translated apps.

Translation seldom corrects latent bugs, can expose latent bugs, and 
can make bugs harder to troubleshoot.

More than a few of the apps built with older compilers or with older 
standards or with permissive compilation options can be less than 
stable.
