This morning, I installed cygwin from the scratch. It comes with cygwin1.dll version 1.1.7-1, perl-5.6.1-1, gcc-2.95-6, and so on... After doing the following work, info crashes with stack dump error. bash$ cd /usr/info bash$ for f in *.info ; do install-info $f dir ; done I went back to cygwin1.dll version 1.1.6-1, and same thing occured. What did I do wrong?
