the quality of g95 varies a lot with the individual binaries. the "stable" version seems quite reliable. even though i encountered a few quirks there as well. the "latest" version of g95 can be pretty good or pretty bad. mind you, the code that i am using g95 on, is using "modern" fortran 90/95 extensively, so it is exercising compilers hard, much, much more than Q-E does. gfortran currently doesn't stand a chance, PGI is a continuous catastrophe requiring many workarounds, and intel is a hit and miss (different compiler versions and patchlevels miscompile different parts of the code, however, most of the time only with full optimization). for this code, the stable g95 has the least problems. so i'd assume the same would hold for Q-E, unless there is some specific code construct used somewhere in Q-E, that g95 doesn't like (happens every once in a while). hope that helps (even though it is not very definite...), axel.
