Repeating crashes featuring Delegate.Invoke, sheet windows

Eric_Williams · February 7, 2014, 2:01am

I’ve got a user who is experiencing multiple crashes per day. I haven’t been able to determine a pattern to the crashes, but I’m having her save the Apple crash reports in the hopes that it would shed some light on what is crashing. There are several basic styles of crash reports; here are the important portions of both:

We’ll call the first one SIGTRAP:

Crashed Thread: 4 Dispatch queue: com.apple.root.default-priority

Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000002, 0x0000000000000000

Does anybody have any idea what is going on here? Thanks in advance.

This user also has persistent crashing whenever a sheet window is displayed. I had to eliminate them altogether. The crashes happen no matter where the sheet window is coming from (a window I designed, a framework window like the Folderitem dialogs, or the Print/Page Setup dialogs). Here is a crash report, apparently triggered by the Page Setup dialog:

This user is running 10.7.5 on a Mac Mini. The application is compiled using Xojo 2014 v4.1.

Joe_Ranieri · February 7, 2014, 2:31am

You should file a bug report with the complete crash reports attached.

Eric_Williams · February 7, 2014, 3:53am

Joe, although I will do that, I hesitate because I can’t provide reliable steps to reproduce it. I can’t even be sure if the crashes are related, especially the sheet window ones. I know from experience that bug reports consisting of “it crashed, here’s the crash report” don’t get results.

Eric_Williams · February 7, 2014, 4:52am

OK, I’ve filed it. I surveyed my crash reports and discovered three categories: crashes from sheet windows; crashes from Folderitem dialogs (apparently via ShowModal and not ShowModalWithin, so they’re not classified as sheet window crashes); and generic crashes that appear to be happening independent of any user-triggered event.

The bug report is here:
