Hi, Thanks for hints from Igor Pechtchanski and Dave Korn. The problem was indeed PATH variable on cygwin side. I made a typo and defined PATH under cmd.exe only as cygwin\bin directory and same invalid address error was result (surprise, surprise :). After few trial/error cycles the fix was to add ClearCase bin directory to the PATH under cygwin !!! Don't ask me why.
However, program is now working properly also if started from bash. Thank you very much for help, Bye, Ljubo P.S. My PATH under windows is huge, and I redefined windows PATH in cygwin to avoid too long "search" times, e.g. if pressing TAB at empty line and similar. However, as my problem shows, this praxis has some risks. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
