Hi,

I've just upgrade my Lazarus to the latest trunk revision on my native FreeBSD system, and in a Linux VM. On FreeBSD the IDE seems to work, and I can use Project Groups.

In the VM I get instant IDE crash with the error message "Invalid floating point operation". I know about previous "index out of bounds" errors, which is believed to be caused by various installed packages. I must add that my Lazarus in the Linux VM has a lot more packages installed than the copy on FreeBSD.

In both cases I used 64-bit FPC v2.6.4 to compile Lazarus. I did a 'make clean' before I did a 'make bigide', and then a "Options -> Build IDE..." to get my custom installed packages.

Anybody else see this error yet?

I did some more testing. As soon as I remove "project groups" package, then the IDE runs fine with my collection of installed packages. Install "project groups", and then I get this error again at startup.

Yes. There seems to be a bug in the IDE menu merging code. It happens only with some combinations of installed packages.

Thanks. Reading old messages from Michael van Canneyt I tried what he suggested, but uninstalling the DataDict packages, but that meant I get an "Exception" a slight change. I then, as a test, backed up my ~/.lazarus/ profile directory and started a completely new one. With the last executable giving me the "Exception" message, using a brand new profile, the IDE started up without problems.

So it seems like configuration settings could also play a roll in this issue.

I'll step by step add my custom configuration settings back in and see what happens.

The combination of packages that triggers this problem is lazdatadict+lazprojectgroups,
the problem appears only when the most recent project groups list is empty (this is when the MRPG submenu is hidden). The problem is an inconsistency on the counts of menu items between some internal list and the physical "project" menu items.

The issue has already a report:
http://bugs.freepascal.org/view.php?id=29675

For myself I fixed the problem here but it has a side effect that prevents me committing the patch, the main menu appears inverted: Help, Windows, Tools, etc... Search, Edit, Files. :)

I'll move my previous profile directory back and retest.

Thanks for the reference, I'll monitor the issue.

It seems the Project Groups package has memory leak to boot as well. I've just reported that:

me committing the patch, the main menu appears inverted: Help, Windows, Tools, etc... Search, Edit, Files. :)

Apply your patch twice, then the menus should be inverted once more - thus back to normal. ;-)

Tested again. Same lazarus executable... all my custom packages installed, minus lazdatadict, plus lazprojectgroups. That executable with a new lazarus profile directory works. That same executable with my previous (normal) profile directory... "Exception" way... I really need Project Groups, so going with the new lazarus profile directory and customizing the IDE once again.

There is already a similar bug report in mantis:
