Agreed, test case is necessary for a definitive fix.

OTOH, looking at the backtrace,
Thread 1 [...]
#7 UMLAttribute::setInitialValue (this=0x0, iv=...) at attribute.cpp:110
#8 0x00000000004f7026 in AdaImport::parseStmt (this=0x2b316b0) at

At adaimport.cpp:620 we have a dereference of  'attr' without preceding check
for NULL pointer:
619    UMLAttribute *attr = static_cast<UMLAttribute*>(o);
620    attr->setInitialValue(initialValue);

The crash is inevitable here (even without knowing the exact use case.)
