Description Dominik 'Rathann' Mierzejewski 2013-02-21 00:02:18 UTC 
Description of problem:
Latest cp2k build fails with this error:
Error: Variable 'row' at (1) not definable inside loop beginning at (2) as INTENT(INOUT) argument to subroutine 'dbcsr_get_stored_coordinates'

Version-Release number of selected component (if applicable):
gcc-gfortran-4.8.0-0.13.fc19

How reproducible:
Always

Steps to Reproduce:
1. try building cp2k-2.4-0.1.20130220.fc19 from git master
2. build fails
  
Actual results:

make[1]: *** [dbcsr_example_2.o] Error 1

Expected results:
Successful build.

Additional info:
cp2k builds fine with F18's gcc-gfortran-4.7.2-8.fc18.

It looks like it's fixed upstream already: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55593
Comment 1 Jakub Jelinek 2013-02-22 15:54:00 UTC 
No, this is a cp2k bug.  The error is correct.
Comment 2 Jakub Jelinek 2013-02-22 16:39:15 UTC 
To expand of this, if you read my analysis of the F19 mass rebuild failures, cp2k has been listed there:
