CONSTANT:
``CONFIGURE_RECORD_FATAL_DUMP_BASE64``
OPTION TYPE:
This configuration option is a boolean feature define.
DEFAULT CONFIGURATION:
If this configuration option is undefined, then the described feature is not
enabled.
DESCRIPTION:
In case
* this configuration option is defined
* and :ref:`CONFIGURE_RECORD_PER_PROCESSOR_ITEMS` is properly defined,
* and :ref:`CONFIGURE_RECORD_FATAL_DUMP_BASE64_ZLIB` is undefined,
then the event records are dumped in Base64 encoding in a fatal error
extension (see :ref:`Terminate`).
NOTES:
This extension can be used to produce crash dumps.

If this configuration option is undefined, then the described feature is not

DESCRIPTION:
In case
* this configuration option is defined
* and :ref:`CONFIGURE_RECORD_PER_PROCESSOR_ITEMS` is properly defined,
then the event records are compressed by zlib and dumped in Base64 encoding
in a fatal error extension (see :ref:`Terminate`).
NOTES:
The zlib compression needs about 512KiB of RAM. This extension can be used
to produce crash dumps.
