:Anything changed with this (with Molcas 6.4) ???

the problem has nothing to do with molcas. g77 does not have a full support for integer*8.

: I compiled the code with g77/gcc, also after ./configure -q64, but in all of the cases I had 32-bit Molcas (DANAME_MF: Requested MaxFileSize is too large!). The 32-bit version works pretty fine (all tests passed) but I couldn't allocate more than approx. 2000MB of memory. Is it also related to 32-bit compilation?

Correct! GA can't allocate more than 2Gb memory, since integers are short.
