I had these failures on AMD64 and FreeBSD -CURRENT. I have to check if that
is either a Linux/FreeBSD or gcc/clang thing. It might still be a gmp vs.
no gmp issue.

This is odd. This might be due ARM differences. GNU Smalltalk doesn't use a
read/write barrier but we mprotect pages and expect a SIGSEGV when these are
being read/written to. It might be that libsigsegv is behaving differently on
FreeBSD.

You could attempt to use "--disable-generational-gc" and if that doesn't make
it more stable you can head to libgst/oop.h and uncomment the define from the
below fragment. If it works better we have an idea where we can look at.

/* Define this flag to disable blacking of grey pages (that is, the
   entire oldspace is scanned to look for reachable newspace objects).
   This is also necessary to run valgrind on GNU Smalltalk.  */
/* #define NO_SIGSEGV_HANDLING */
