It might be a problem because it's a false error and not exactly clean. Granted, testing such things is not that straightforward. Platforms such as Windows do have a feature where you can tell it to randomly fail memory allocations after about 8 minutes of start time (so the machine can fully boot up) - the trouble is that graphical elements on the desktop stop being rendered properly, among other failures, and you can't predict where an allocation will fail in the program. I think you can put in exceptions so allocations don't fail for Lazarus or the Command Prompt, for example. The trouble is, these allocation failures are designed for C programs, where "malloc" returns NULL if memory isn't allocated. Free Pascal's GetMem raises an exception instead. Granted, it shouldn't be too much of a struggle to implement a custom memory manager for testing and to cause random (or deterministic) allocation failures to see how cleanly the situation is handled. It could be a fun test suite! It is times like these that give weight to being careful with memory allocations. I started programming in the mid-90s where memory was still quite tight (namely, a computer running Windows 95 with only 8 MB of RAM!) While computers are very fast and spacious today, the same standards still apply in places, notably in tight loops and functions that get executed very frequently. Gareth aka. Kit
On Mon 30/07/18 19:24 , "Anthony Walter" sys...@gmail.com sent: I thought I'd add a point about compiling and memory. On the Raspberry Pi, I know for a fact that building the compiler can fail after a while due to insufficient memory. When this happens the problem with no memory doesn't present itself as such. Rather you're left with an error indicating a problem with the source. I've gotten around this problem by making the compiler without a desktop environment running and re configuring the swap size. Might this problem be related in some way to the discussion in this thread? _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel [1]">http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel Links: ------ [1] http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
