The problem was upstream in Eclipse Prolog Source code= . Has been resolved now. You may consider the issue closed. Only one query. Cygwin is a good idea and works well. But is it weaker in = GUI and multithreaded as compared to msys2? Kindly advise Warm regards, Manu Get Outlook for iOS ________________________________ From: Manu goswami Sent: Thursday, July 29, 2021 5:29:58 PM To: cygwin@cygwin.com Subject: Re: CYGWIN + windos10 + eclipse clp prolog Hi Brian, Thanks for the reply. Eclipse clp is a version of open source prolog and had been running success= fully on my computer for some months. There has been no change in source code. What new I did was to install msys2 and call a particular Cygwin compiled e= xe from msys2. The called Cygwin compiled .exe did run from msys2 but most= probably crashed Cygwin causing segmentation fault ever since. Surprisingl= y the called Cygwin compiled .exe runs successfully but eclipse clp prolog = .exe fails. Should I remove msys2 ? as I have reinstalled Cygwin multiple times ever si= nce this error occurs.

If you want to see replies to your questions, subscribe to the mailing list, or view the replies on one of the many web based message archives of the mailing list, including that at cygwin.com. Report upstream to wherever you got the sources for whatever "eclipse clp prolog" is - in whatever language(s) they use - web links to projects and sources are more informative than garbled buzzwords. SIGSEGV is a symptom of a programming error - out of bounds access - caused by following the wrong pointer to an invalid location, using a NULL pointer, array or buffer index incorrect, use after free, incorrect object size or indirection, just to suggest some of the most frequent and common causes. If you have made your own local and/or recent changes to the sources, they are invariably the likely cause of the issue, so recheck any recent local work very carefully. The Cygwin project provides packages for execution and development but, as Cygwin is an all volunteer effort, with limited personnel each with limited time, so all projects built using those packages are the responsibility of those projects downstream of Cygwin, otherwise we would not have any time to maintain and expand the packages supported. -- Take care.
