Not that countless. Personal experience reports one bug in 8 years of
use... Just as was previously mentioned in this thread:
 * check your hardware
 * know your FEATURES and howto test failures when some are enabled

it's just like any package failing with some gcc/linked/whatever flag,
you just don't stop using that flag where it works just because of one
package, nor do you stop using gcc.
