Hi Raymond,
most regulars are traveling (and are meeting this weekend at FOSDEM in
Brussels).
I already recommended the try to find whether any exceptions are thrown
(and caught away) during the steps you already debugged.
In gdb I'd use the command
catch throw
to find the throwing code. Maybe there is similar facility in Solaris
Studio?

Subject: OO 4.01 Compiled for Solaris 11 x86 Runtime Memory Fault
We've recently compiled OpenOffice 4.01 on Solaris 11 x86 and are experiencing
the following at runtime. I've included some of the stack trace below. Any help
would be great. Thanks!
Observed Behaviour
1. OpenOffice starts, the splash screen with logo appears and then
closes replaced with the full application window and choices for specific
OpenOffice projects.
2. Selecting either the Word or Spreadsheet project causes a
segmentation fault and closes the application.
3. Following the start of the application with the debugger, we can
see the SidebarController is created in a first pass without error (known
because first time to this stop point does not error).
4. As the process continues, the SidebarController constructor is
called a second time (unknown why, but could be understood with more
familiarity with the system).
5. The failure doesn't appear in the constructor, but the trace follows down
SidebarController constructor call of "WeakReference<SidebarController>
WeakController (this);"
6. This template definition for WeakController uses
Reference<Template>::Refrence( interface_type *pInterface) as its definition in
::com::sun::star::uno::Reference.hxx.
7. The function will try to convert the pInterface parameter to a
XInterface type called _pInterface.
8. If it succeeds in converting the pInterface to _pInterface then
the function will try to acquire a new reference.
9. Assumption: Creating this new reference calls
SidebarController::notifyContextChangeEvent with a corrupt or bad rEvent. This
assumption is based on the stack where the immediate next routine after the Reference
function call is the notifyContextChangeEvent, also while following along in the
debugger, the rEvent parameter at this point is already corrupted with the value
<ERROR> stored in the structure.
10. It is later after the notifyContextChangeEvent calls Context and
then ustring that the segmentation fault occurs, but I believe the error
located in rEvent is what causes this later problem.
It appears as if inside the SidebarController Constructor at line 168 when
xWeakController(this) is called that the problem first occurs. The xWeakController
appears to be defined in Reference.hxx in /cppu/inc/com/sun/star/uno/ and this
definition as an inline function that calls the _pInterface->acquire() at line 136.
We assume that this acquire is where the problem occurs because the
SidebarController::notifyContextChangeEvent (which is the next item on the stack) rEvent
contains an <ERROR> value in the dbxtool (debug tool) immediately following in the
stack. It eventually crashes downstream at line 103 of ustring.hxx in /sal/inc/rtl when
the string is trying to be accessed as pData = str.pData;
Stack Trace:
(dbx) where
current thread: t@1
=>[1] rtl::OUString::OUString(this = 0xfeff9dac, str = CLASS), line 103 in
"ustring.hxx"
[2] sfx2::sidebar::Context::Context(this = 0xfeff9dac, rsApplication = CLASS,

[5] sfx2::sidebar::SidebarController::SidebarController(this = 0xebc6d6b0,
pParentWindow = 0x9659bf8, rxFrame = CLASS), line 168 in "SidebarController.cxx"
I can provide more of the stack trace if needed. Thanks in Advance!
