What was happening is that the TextStream object is reused for multiple
|
|
different files. Therefore, when one calls setStream(nullptr) or
|
|
setFile(nullptr), m_f or m_s will, respectively, still contain a pointer
|
|
to the previous member, which is used when one calls setFile() or
|
|
setStream() again, since these methods will call flush().
|
|
|
|
For example, a program doing
|
|
|
|
s.setFile(f1);
|
|
s.setStream(nullptr);
|
|
fclose(f1);
|
|
s.setFile(f2);
|
|
|
|
will call fwrite(f1, ...). This pattern can be observed in many parts of
|
|
Doxygen, so fixing it in TextStream itself by always zeroing the other
|
|
pointer is the simplest fix.
