            Bug ID: 110997
           Summary: Some forms stall with 100% on open
           Product: LibreOffice
           Version: 5.4.0.3 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Base
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: tim at tim-passingham.co.uk

Description:
I have some quite complex forms with several subforms, which when opened stall,
with CPU at 100%. This is new in 5.4.0.3 (both direct from Libreoffice and via
ubuntu ppa).  Version 5.3.4.2 is OK.

Steps to Reproduce:
1. Open a form from another form providing a filter
2. Form displays, but goes grey
3. Waits forever, CPU at 100%

Actual Results:  
Not sure what I can add. 

Expected Results:
Nothing - just hangs.


Reproducible: Always

User Profile Reset: No

Additional Info:
This happens on non-trivial forms.  I don't know exactly what the crucial
factor is.  Some, mainly simpler, forms open OK. My database is in Mariadb on
another system on my LAN. I have tried both MYSQL (native) and MYSQL (JDBC)

It would not be at all easy to provide a demo, since the forms are complex,
with macros, filtering dialogs, and data resident on another system.

IF you have any ideas how I can diagnose this hang, please let me know. I'm
willing to install a debug version of LO if needs be.
