Uninitialized Variables at Run Time

g77 needs an option to initialize everything (not otherwise explicitly initialized) to "weird" (machine-dependent) values, e.g. NaNs, bad (non-NULL) pointers, and largest-magnitude integers, would help track down references to some kinds of uninitialized variables at run time.

Note that use of the options -O -Wuninitialized can catch many such bugs at compile time.
