What is worse than things not working is when things start working and I don't know why.
After a hiatus in PHP land, I am back to Squeak Land and lo and behold, the Stack Interpreter 32 bit compiled and runs the 4.6 image.
That is if what you see below is in fact the Stack Interpreter.
Please let me know if it is not

If so, then we have a second data point of building a Stack Interpreter on a 64 bit machine with 32 bit compat libs.

An interesting point of note is of note is that I was getting ready to debug a vm that would not run.
It was built with this configure command.
../../../platforms/unix/config/configure CC="gcc -m32" CXX="g++ -m32" --without-npsqueak CFLAGS="-g -O2 -msse2 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0 -DDEBUGVM=0" LIBS=-lpthread --x-libraries=/usr/lib --prefix=/home/tty/usr/local/stackVM32
and the result was a vm that built, but would hang waiting on what I believed was a signal.
Setting out to debug this non-running vm, I changed to -O2 flag to -Og which rhymes with 'd' and that spells "debugging".
../../../platforms/unix/config/configure CC="gcc -m32" CXX="g++ -m32" --without-npsqueak CFLAGS="-g -Og -msse2 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0 -DDEBUGVM=0" LIBS=-lpthread --x-libraries=/usr/lib --prefix=/home/tty/usr/local/stackVM32
And, lo and behold, no more trouble in River City. It ran.
