<p>Panics with this category are raised on the user side by member functions

of T type and R type classes, which reside in the <filepath>euser.dll</filepath> file. </p>

<p>They are also raised by some static member functions of the <xref href="GUID-C197C9A7-EA05-3F24-9854-542E984C612D.dita"><apiname>User</apiname></xref>, <xref href="GUID-C5D0C7E7-061F-3BA5-AE24-B83237684B01.dita"><apiname>UserHeap</apiname></xref> and <xref href="GUID-EFAFDD75-7E59-306A-882D-317F5564979E.dita"><apiname>RHeap</apiname></xref> classes.

Typically, they are caused by passing bad or contradictory values to class

constructors or member functions. </p>
