The following works in PyQt4, but I did not heavily test. For tests I did see the uploaded file. Perhaps this could be converted to C++?

from PyQt4.QtCore import QTextStream, QString

#subclass QTextSream
class MacAwareQTextStream(QTextStream):

    def __init__(self, qstring):
        QTextStream.__init__(self, qstring)
        self.newline = None

    def readLineWithNewline(self, newline, bufferlen=128, prefix=QString("")):
        start = self.pos()
        buf = self.read(bufferlen)
        if buf.contains(newline):
            pos = buf.indexOf(newline)
            line = buf.left(pos)
            if not self.seek(start+pos+newline.length()):
                self.seek(line.length())
            return line.prepend(prefix)
        elif buf.length() < bufferlen:
            #is last line
            return buf.prepend(prefix)
        else:
            #try bigger buffer
            return self.readLineWithNewline(newline, bufferlen*2, buf.prepend(prefix))

    def findNewline(self, bufferlen):
        buf = self.read(bufferlen)
        if buf.contains("\
\
"):
            return QString("\
\
")
        elif buf.contains("\
"):
            return QString("\
")
        elif buf.contains("\
"):
            buf2 = self.read(1)
            if buf2 == "\
":
                return QString("\
\
")
            else:
                return QString("\
")
        elif self.atEnd(): #no new line in file
            return QString("\
")
        else:
            return self.findNewline(bufferlen*2)

    def readLine(self):
        bufferlen = 1024
        if self.newline is None:
            #need to determine newline chars
            self.newline = self.findNewline(bufferlen)
            self.seek(0)
        return self.readLineWithNewline(self.newline, bufferlen)

I confirm this bug for 2.14 (Essen) and 2.2 (Valmiera).

Usually GIS users aren`t nessesarly IT experts, it would be nice, if QGIS avoids crashes by unexpected data :)

I see your point, that the bug couldn't fixed upstream at the component itself. On the other hand, it would be nice when there would be an embedded workaround.

My usecase was: http://koenigstuhl.geog.uni-heidelberg.de/~mover/rostock.zip

End of life notice: QGIS 2.18 LTR

Source:
http://blog.qgis.org/2019/03/09/end-of-life-notice-qgis-2-18-ltr/

QGIS 3.4 has recently become our new Long Term Release (LTR) version. This is a major step in our history – a long term release version based on the massive updates, library upgrades and improvements that we carried out in the course of the 2.x to 3x upgrade cycle.

We strongly encourage all users who are currently using QGIS 2.18 LTR as their preferred QGIS release to migrate to QGIS 3.4. This new LTR version will receive regular bugfixes for at least one year. It also includes hundreds of new functions, usability improvements, bugfixes, and other goodies. See the relevant changelogs for a good sampling of all the new features that have gone into version 3.4

Most plugins have been either migrated or incorporated into the core QGIS code base.

We strongly discourage the continued use of QGIS 2.18 LTR as it is now officially unsupported, which means we’ll not provide any bug fix releases for it.

You should also note that we intend to close all bug tickets referring to the now obsolete LTR version. Original reporters will receive a notification of the ticket closure and are encouraged to check whether the issue persists in the new LTR, in which case they should reopen the ticket.

If you would like to better understand the QGIS release roadmap, check out our roadmap page! It outlines the schedule for upcoming releases and will help you plan your deployment of QGIS into an operational environment.

The development of QGIS 3.4 LTR has been made possible by the work of hundreds of volunteers, by the investments of companies, professionals, and administrations, and by continuous donations and financial support from many of you. We sincerely thank you all and encourage you to collaborate and support the project even more, for the long term improvement and sustainability of the QGIS project.
