I am using b18 as downloaded from Cygnus, and Mingw32 version 0.1.4 > from http://www.geocities.com/Tokyo/Towers/6162/ I have tracked this down (eventually) to an attempt to free memory twice (two pointers to the same thing). This code has been working without a runtime error for four years, under Sun C (Solaris SPARC), IBM C (AIX RS/6000), and Cygnus b17. It has taken this new version (b18+Mingw32) to bring it to light. -- John Cooper (JPSC Ltd, UK) - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request AT cygnus DOT com" with one line of text: "help".
