I'm new to GNU st so I don't know the answer, but when reading your message, 
some questions arise.

Actually first of all I wonder myself whether GNU gst 3.2.91 is the latest 
and whether any development is still going on ?

(version from 2015

How exactly was GNU st configured and built ? 

What's the version and operating system ?

Did you build a 32bit or a 64bit gst ?

For example:
#smalltalk-3.2.91$ file gst
gst:      ELF 64-bit LSB executable AMD64 Version 1, dynamically linked, not 
stripped, no debugging information available

Was 'gmake check' reporting any failed checks ?
