[FLASH-BUGS] FLASH 2.3 on SUN - compiler bug?

[Claudio Dalla Vecchia]

Hi everyone,
these days I am visiting Urbana University - before coming to the
conference in Chicago - trying to setup a cosmological simulation.

I wrote some code to input particle positions/velocities/masses and it wor
fine, mapping on the grid their density, and so on...

Adding a new routine to setup the gas properties on the mesh, I am using
particle density 'pden', as computed by 'MapParticlesToMesh'.  I realized
that, after calling 'ParticleToMesh', temp_buff2 has the right value of
density, but solnVec doesn't change.  I mean, copying temp_buff2 to
solnVec, doesn't work, and the 'pden' subarray comes out with the same
initial values.

This could be either a coding bug - some non standard Fortran procedure -,
or a compiler bug.  I have no idea about what is going on.

The machine I am using is a 24 processors SUN with:

	SunOS titania 5.8 Generic_108528-22 sun4u sparc SUNW,Sun-Fire
	f95: Forte Developer 7 Fortran 95 7.0 Patch 111714-06 2003/04/10

The Makefile.h is attached.
The FLASH version is 2.3

Thanks,
Claudio.

# Compilation flags
#
#  Three sets of compilation/linking flags are defined: one for optimized
#  code, one for testing, and one for debugging.  The default is to use the 
#  _OPT version.  Specifying -debug to setup will pick the _DEBUG version,
#  these should enable bounds checking.  Specifying _TEST is used for 
#  flash_test, and is set for quick code generation, and (sometimes) 
#  profiling.  The Makefile generated by setup will assign the generic token 
#  (ex. FFLAGS) to the proper set of flags (ex. FFLAGS_OPT).

# Library specific linking
#
#  If a FLASH module has a 'LIBRARY xxx' line in its Config file, we need to
#  create a macro in this Makefile.h for LIB_xxx, which will be added to the
#  link line when FLASH is built.  This allows us to switch between different
#  (incompatible) libraries.  We also create a _OPT, _DEBUG, and _TEST
#  library macro to add any performance-minded libraries (like fast math),
#  depending on how FLASH was setup.
