[ferret_users] parsing in go-files fails

[Martin Schmidt <martin.schmidt@xxxxxxxxxxxxxxxxx>]

Hi,
in the latest ferret version, v7.4,  an error found in v7.3 is still 
alive. A least a little bit.

machine>/sw/viz/ferret/py_ferret_v74_os423_py_2713/ferret
        NOAA/PMEL TMAP
        PyFerret v7.4 (optimized)
        Linux 4.4.126-48-default - 04/29/18
        22-May-18 15:49

yes? go multi_view 3, 5, 0.15, 0.1, 0.03, 0.25, 0.10, 0.022, , 0.05,0.035
 **ERROR: invalid subcommand: mv_r    = 3
defiymbol mv_r    = 3
Command file, command group, or REPEAT execution aborted

Opening data sets and rendering images works well otherwise.

I compiled pyferret by myself. The compiler is gcc-5, linux is OS42.3. 
Compiler flags are left as recommended. python is python2.7 coming with 
the system.  The code works well on one machine but the identical binary 
fails on other machines with the same OS42.3-system, all are 64-bit 
systems.
- ldd applied to libpyferret.so gives identical results on both machines 
(after removing the address-information)
- the user environment is "similar"
The major difference is that the code is build on a E7-8893 v4 CPU. It 
works there. For many other software (including ferret v22) those 
binaries run on other platforms with E5 and i5-CPUs. No hardware 
specific optimisation flags were used. We are maintaining a common 
software pool this way, it works for many software packages.

I do not know, where in the code parameter parsing for go-scripts or 
go-script parsing is done. The error message "defiymbol mv_r" suggests a 
local memory problem or a problem with function parameter types?

All suggestions or help would be very welcome.

Greetings,
Martin Schmidt
