Lazarus crashes

[mj]

Lazarus often crashes on my computer. Usually it happens when I search with control-F. It also crashes sometimes when I switch tabs, type a variable name, or scroll up/down. The message it gives me is:
Access Violation

Press OK to ignore and risk data corruption
Press Cancel to kill the program


This is on windows 7 with Lazarus v. 1.6 64bit.
I have tried verifying the integrity of the installer and did a clean reinstall. Is there a crash dump file I can find that might have more information?

Start Lazarus with --debug-log=path\to\debug-log.txt
Alternatively start Lazarus from within the debugger (gdb), let it crash then inside the debugger type "bt" (wihtout the quotes) to get a backtrace.

For both solutions Lazarus must be build with debug info.

Hi

I also encounter some crashes, but on MacOS how to add the --debug-log parameter?

This is on windows 7 with Lazarus v. 1.6 64bit.

v1.6 is quite old, its very likely that what ever is worrying you has been fixed since then. And I think there is little chance of anyone fixing 1.6 if you do manage to track down the problem.

Is the a reason you are using v1.6 and not the current v2.0.10  ?

I am using 2.0.10.

I am using 2.0.10.

when it crashes does macOS offer you an error dump?
if yes, could you please provide a copy of it?

Many suggestions already given. I'll give you different direction.

I am a computer technician. For your case I suggest you to download some free 3D games and play them for several hours. If it does not crash then it passes.

For further test, you can search the Internet and download a free tool called computer stress test. If it passes all the tests then your computer is okay.

Why does a computer crash? There are many possibilities. The hardware, the VGA/GPU, the Windows, the drivers, infected by virus/malware, the bug in the program itself.

Lazarus is not bug free. But Lazarus 1.6 wasn't that bad. It doesn't crash once every several days. My Lazarus IDE never crash, not even once, unless I use it to run ugly code so the debugger crashes.

Well no, I have the dialog box saying:

Press OK to ignore and risk data corruption
Press Cancel to kill the program

The thing is on MacOS, I don't run LazPaint from the command line, it is an app. Hence my question: how to add the --debug-log parameter?

Lazarus often crashes on my computer. Usually it happens when I search with control-F ...

There is some bug lurking under the search / replace stuff but nobody could reproduce it properly.

However it does not explain your other crashes.

You can start it from the command line, you have to use the app bundle as a binary name. I tell my users to get a debug log of tomboy-ng like this -

Code: [Select]

open /Applications/tomboy-ng.app --args     "--debug-log=$HOME/tomboy-ng.log"  "--debug-sync"
You can probably directly edit the app bundle too, its just a directory. try google ...

Ok thanks. So I have made a script with Script Editor and then exported it as Lazarus-debug.app in the Applications folder. Works fine. Here is the code:

Code: AppleScript  [Select][+][-]

1. do shell script "open -a /Applications/Lazarus.app --args \"--debug-log=$HOME/lazarus.log\" \"--debug-sync\""

Next time it crashes I will be ready.

Try to catch it more than once, if it really is a software problem I'd expect the failure to be consistent.

I agree with what others are saying: by and large the IDE is robust, and I certainly use ^F searches enough to notice any problem.

/However/, I'm typically running on Linux and there's always a possibility that your installation has something unusual in it... odd keyboard handler or something like that.

In fact it reminds me of something that I used to see with one particular version of Delphi if run under Qemu virtualisation: so a "Search files" and it would crash the emulator.

So if people do appear to be sceptical, you need to try to work out what you've got that's unusual.

It's not crashing when searching. I don't even remember when. Just that when it happens, the message does not help much.

In OP's case, it was crashing when searching. You've hijacked his thread :-)

Sort of. But the title is generic and that was the first and main search result.
