[MLton-devel] gcc/ld bug

I built a gcc 2.95.3 cross-compiler, and it segfaulted in exactly the
same way.

I tried this, but I obviously don't understand how to use -r.

% gcc -b i386-pc-cygwin -r -o z.o mlton.*.o
% gcc -b i386-pc-cygwin -r mlton.o z.o
z.o: file not recognized: File truncated
collect2: ld returned 1 exit status
% file z.o
z.o: 80386 COFF executable not stripped - version 30821
% file mlton.o
mlton.o: 80386 COFF executable not stripped - version 30821

I tried this, but it fails in the same way.
