             Bug #: 30465
           Summary: BridgeCentral: Invalid floating point operation in
                    mozjs.dll (fldcw in JSDOUBLE_IS_INT32)
           Product: Wine
           Version: 1.4
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: mshtml
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: u.dickow at gmail.com
    Classification: Unclassified


When BridgeCentral 2.2.3 is logged in to a club database on the Internet, it
will be fatally hit by an "Invalid floating point operation" dialog box after
at most (and often exactly) 9 minutes of operation, i.e. 9 minutes after
opening of the main window displaying the very simple web page
http://bridge.dk/bridgecentral/nyheder/Welcome/Welcome.html .  When you press
OK to the dialog box, the application is either completely confused and
unusable, or it immediately crashes with 2 more dialog boxes about Access
violation in mozjs.dll for read of an address, and the general wine "Serious
problem" box.  The crash happens completely reproducibly if you just let the
application wait at the Welcome window after login and don't touch it.

"Unfortunately" (from a debugging point of view) the bug does _not_ appear when
BridgeCentral 2.2.3 uses only a local database, without any Firebird TCP
connection.  So although anyone can download BridgeCentral from
http://bridgecentral.dk/ , you cannot easily reproduce the bug without being a
privileged member of a Danish DBf bridge club.
