<varlistentry><term>out of memory</term>
<listitem>
<para>
Compiler dynamic memory overflow. The compiler requires
dynamic memory for symbol table entries, block level
declarations and code generation. Three major factors affect
this memory usage. Permanent declarations (those appearing on
the outer block level (used in include files)) must be
reserved from the dynamic memory for the duration of the
compilation of the file. Each { causes the compiler to perform
a block-level recursion which may involve "pushing down"
previous declarations which consume memory. Auto class
initializers require saving expression trees until past the
declarations which may be very memory-expensive if may exist.
Avoiding excessive declarations, both permanent and inside
compound statement blocks conserve memory. If this error
occurs on an auto initializer, try initializing the value in
the code body.
