There is a regression in 4.2 from 4.1 with fixed-form literal character constants that are continued to a new line. Consider the following fixed-form code:
program a character(len=90) c c A tab is between 9 and 0. c = '1234567 &89 0' print *, c end The output with 4.1 and trunk are kargl[216] gfc41 -o z a.f kargl[217] ./z 1234567 89 0 kargl[218] gfc4x -o z a.f kargl[219] ./z 123456789 0 gfortran 4.1 agrees with the output from NAG's compiler and with g77. -- Summary: [4.2 Regression] fortan fixed-form literal character constant not padded.
