No, but I don't compile the collections, I just buy them.

I pointed out earleir that many collections offered in the '70s and '80s, and I presume earlier although I don't recall seeing any of them, identified
Das Lied as symphony #10. Here's what the non-definitive Wikipedia has to say about it:
Curse of the ninth
Mahler was obsessed by Beethoven's legacy; he declared that all of his symphonies were "ninths", having the same impact and scale as Beethoven's famous Choral symphony. Mahler was also apparently a firm believer in the curse of the ninth and thus terrified of writing a ninth numbered symphony. This is held to be the reason why he did not give a number to the symphonic work - Das Lied von der Erde - which followed his Eighth, but instead described it merely as Eine Symphonie für eine Tenor- und eine Alt- (oder Bariton-) Stimme und Orchester (nach Hans Bethges "Die chinesische Flöte") (A symphony for one tenor and one alto (or baritone) voice and orchestra, after Hans Bethge's "The Chinese Flute"). The work can be considered a combination of song cycle and symphony. As it happened, Mahler did in fact die after writing his ninth numbered symphony, leaving his tenth unfinished. There have been several attempts to complete the work (or produce 'performing versions' of the draft) since the 1940s.
Some compilations also refer to Symphony #7 as the
Song of the Night, although Mahler did not use that name himself. I suppose there is a precedent for doing that sort of thing, but it's not my area of expertise.
I suppose it could be argued that, since he died two years after
Das Lied was completed, he simply never got around to numbering it.
Did he actually assign the number 10 to the tenth symphony fragment, or was that designation assigned by others? The Wikipedia entry would indicate that he did not do so - perhaps he would have called it the eleventh.
