Now I compile racket with GCC 4.6 because this version has TLS support emulated but I think this workaround is adding other bugs to racket. Is it possible to compile racket in a OS/compiler without thread-local storage?. My configure options: --enable-libffi --enable-gracket --enable-jit --enable-foreign --enable-places --enable-float --enable-docs --enable-pthread --enable-lt=/usr/bin/libtool --enable-futures </blockquote> Thread-local storage is needed for `--enable-places' and `--enable-futures', so you just have to leave those out to compile without it. </blockquote> </div></div> What do Racket's thread cells do when Racket is compiled without TLS?
