I downloaded latest stable CVS code (1.11.2) and compiled it under cygwin.
"cvs co", "cvs login" and "cvs commit" worked, but not "cvs update".
I traced the bug to call to
open (".", O_RDONLY);
at lib/savecwd.c:61 in CVS source. This call is made the same way during
commit and update, yet it fails during update only, with the error "file
When I tried to make similar call from other places in the code, I
learned that placing the call right before save_cwd is called from
recurse.c makes the entire thing work.
The next thing I tried was optimization level in the compiler. When I
replaced -O2 with -O, the whole situation went away.
I am running Windows ME.
GCC gives the following in response to -v :
$ gcc -v
