Re: [fpc-pascal] unexpected termination with no errors
For anyone who didn’t see in in my other message.. the only reason I didn’t see the debug info before was because I was redirecting stderr to a file then echoing the file to the screen.. but with a full disk, no more could be written into my log file, therefore the file ended just before the error. It’s the one case the logging stderr to a file the echoing the file to console could not work. Widnows doesn’t have a really good way to send output to the console and a file at the same time. In combination with this the errorcode being displayed as a negative number put it into the category of “things zero or less” which made my batch file treat it as a normal exit. It was my batch file that was failing to function correctly.

Windows represents exception codes as an unsigned int. The error -1073741819 is actually0xC005.

[fpc-pascal] unexpected termination with no errors
A program I have been working on for years has suddenly developed a bug in it and at a certain point, it is just terminating and not giving me any runtime errors or any error of any kind. It's just running running... running... then BAM - GONE, no explanation%errorlevel% is -1073741819 I have been trying to track it down by putting writeln's in my code before and after the section that is causing me the problem, but without the diagnostic information I normally get, this is very tedious.I am at a point now where I've determined that it's something in a data processing loop that has hundreds of case statements... If I try to writeln all so I can see what's the last thing it wrote to the console before it crashed, it takes so long to run it's going to take me a very long time. If I had the runtime error or some kind of information, I would have fixed this in minutes, but doing it this way has already taken me hours. I wrote a sample program that generates a runtime error on purpose and it's working fine... I get the normal runtime error output I always do telling me what the problem is and what line number it's on.. etc... The strange thing about this bug is that I can run the program on the same computer successfully in my development directory but it crashes when it's in another installation I have for pre-release testing... so it's not crashing when I run it from the FPC text IDE.. but when I move the executable over to my pre-release testing directory, then it is crashing like this with no indication of anything except the strange errorlevel being set. Has anyone encountered anything like this before or know how I can make sure I always get the maximum amount of debugging info when my program crashes? ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
