[MITgcm-devel] g77 on darwin does not compile w2_print_e2setup.F

[Martin Losch]

Hi there, I am getting an error when running "testreport -t  
global_ocean.cs32x15":

g77 -Wunused -ffloat-store  -O0 -c w2_print_e2setup.f
w2_print_e2setup.f: In subroutine `w2_print_e2setup':
In file included from w2_print_e2setup.f:0:
w2_print_e2setup.f:1060: internal compiler error: in  
instantiate_virtual_regs_lossage, at function.c:3746
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
make: *** [w2_print_e2setup.o] Error 1
make: Target `all' not remade because of errors.

And this is the statement (appears twice) that causes this error (at  
least the error goes away, when I comment it out):
            IF ( ii.NE.0 ) cc1 = edge(ii)
I can make it  compile by changing
       CHARACTER*1 edge(4), cc1
to
       CHARACTER*1 edge(4)
       CHARACTER*2 cc1
which is certainly not what the programmer intended, but maybe it give  
you a hint, why this is happening and how it can be fixed.

PS. I think g77 is no longer continued so I am not sure if it makes  
sense to send a bug report
