Hi

I am one of the homebrew-science maintainers. We updated to the latest gcc version an are getting this error, while building abinit:

m_vcoul.F90:352:24:
call random_seed(put=seed)
1
Error: Size of 'put' argument of 'random_seed' intrinsic at (1) too small (12/33)
make[3]: *** [m_vcoul.o] Error 1
make[3]: *** Waiting for unfinished jobs....
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

I think the seed size for the put argument needs to be dynamically calculated first.
Could you please have a look? A patch would be greatly appreciated.

Thanks for having a look at this. The provided link does not work though.

Hi,

sorry for the link : access restricted

but, you can use this workaround :

I did that, but I used 33 (based on the error message), and it worked (at least it compiles). So we have a workaround for the moment:)
