[Bug optimization/14019] New: fortran if statement with .and. causes optimizer to produce wrong code

[mmrashid at ucdavis dot edu]

A short fortran program compiled and loaded with g77 causes the following
problem:  an if statement within a do-loop that contains two logical expressions
separated by .and. causes the code above the if statement, and inside the loop,
to not be executed (i.e. it is skipped over).  This only occurs when invoking
g77 with any level of optimization.
