gfortran #3

Open mee067 opened 1 year ago

mee067 commented 1 year ago

Compiled the 1860 code using gfortran (the default when just using make) successfully but it gives memory errors (for several setups) when run. These same setups run fine when compiled using intel 2018 (make ifort). Is there a particular version of gfortran that need to be used? I compiled using 5.4, 6.4, 7.3, and 9.1 all give the same run-time error: Program received signal SIGSEGV: Segmentation fault - invalid memory reference Ther error occurs right after reading all the configuration files and checking the forcing files before it prints "DONE INTITIALIZATION"

r1813 compiles and runs with gfortran

Can you compile with symbols to see if it tells you where it happens or point me to example files I can use to replicate?

mee067 commented 1 year ago

I compiled it with gcc 7.3 adding symbols (make symbols). This is the result when I run:


Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Any version of gcc >= 5.4 should work fine. The makefile checks the version and stops if it's not compatible. Do these setups use outputs_balance.txt? If so, what fields are active for what time-output frequencies? Second, the identified line points to an 'end if' statement, where I would expect it to point to a line using a variable. Have you made modifications to output_variables.f90?
