Depending on the current compiler directive {$H+} (default for any
lazarus program) type string will be ansistring.
If you write a record with a variable of type ansistring to file, it
will write the pointer to that string.
If you read that file, this poiter probably will point to something
you have no access to --> SIGSEV

Change all string explictely to ShortString in the definition of your record.
