--- Comment #8 from John <jwmwalrus at gmail dot com> --- Hi, It seems that some testing was required after all. With the latest gcc snapshot from Debian (20150329-1) I still get the same output from the test code: $ ll `which gfortran-5.0 ` lrwxrwxrwx 1 root staff 35 Feb 26 11:01 /usr/local/bin/gfortran-5.0 -> ../../lib/gcc-snapshot/bin/gfortran* $ gfortran-5.0 test_namelist.f90 $ ./a.out $ cat some.dat &SOME A+T2+T1%I= 0, A+T2+J= 0, A+K= 0, / In my actual code, what fails is READING a namelist generated by a previous version of gfortran, so maybe that needs some checking as well? System and compiler information follows: $ lsb_release -rd && gfortran-5.0 -v Description: Debian GNU/Linux 8.0 (jessie) Release: 8.0 Using built-in specs.
