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 version,
and whether any development is still going on ?
(version from 2015 https://alpha.gnu.org/gnu/smalltalk/)
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 ?
