Thanks Marco,

Looks like problem may be memory allocation in mkshortcut.c(xstrndup), so have 
attached patches to apply to that source (from cygport? or amnually), and to p-i 
script to get strace.

So could you please apply the attached patch to /etc/postinstall/cygwin-doc.sh, 
and retry your manual p-i script rerun prefixed with CYGWINFORALL=-A 
/etc/postinstall/cygwin-doc.sh (may need elevated admin rights), and save that 
strace output; then retry your cygwin-doc setup, and save that strace output; 
then apply the attached mkshortcut.c patch, rebuild mkshortcut, retry your 
cygwin-doc setup, and save that strace output.

Hopefully the last try will no longer fail, otherwise I will have to set up my 
environment to reproduce the error.
