Parsing incomplete XML raises an XMLSyntaxError. But if a bespoke target is used, it fails to instantiate the error:
parser = etree.XMLParser(target=etree.TreeBuilder())
etree.fromstring('<a><b></b>', parser=parser)
The following raises the error correctly:
parser = etree.XMLParser()
etree.fromstring('<a><b></b>', parser=parser)
It looks like TreeBuilder.close() calls (https://github.com/lxml/lxml/blob/master/src/lxml/saxparser.pxi#L820):
raise XMLSyntaxAssertionError("missing end tags")
Which calls the XMLSyntaxError constructor with only two arguments (self and message) and not the expected 5.
Python : sys.version_info(major=3, minor=8, micro=13, releaselevel='final', serial=0)
lxml.etree : (4, 9, 1, 0)

which calls the XMLSyntaxError constructor with only two arguments (self and message) and not the expected 5.
This issue also surfaces when any error is raised while processing the XML, which finally closes the TreeBuilder and throws another exception, because the processed XML has unclosed tags (as processing is half-way done).
