Hello,

my first guile code started with a SIGSEGV.  Not sure if
it's not my fault but looks like a bug to me.

| {
|         SCM str = scm_makfrom0str ("hello world");
|         return 0;
| }

I just installed guile-1.6.4 myself using

$ ./configure --prefix=$HOME --with-threads --enable-debug-freelist --enable-debug-malloc --enable-guile-debug --disable-deprecated

I'm not on any lists, so if there's something interesting
for me please Cc: to me.
