--- Comment #4 from Julien Nabet <serval2412 at yahoo.fr> ---
On pc Debian x86-64 with master sources updated 3 days ago, I could reproduce
this.
This assert is triggered because it's a SwGrfNode
$4 = (SwNode &) @0x555558385210: {<BigPtrEntry> = {_vptr.BigPtrEntry =
0x7fffca649208 <vtable for SwGrfNode+208>, m_pBlock = 0x555557861a90, m_nOffset
= 18}, 
  m_nNodeType = SwNodeType::Grf, m_nAFormatNumLvl = 0 '\000', m_bSetNumLSpace =
false, m_bIgnoreDontExpand = false, static s_nSerial = 89, m_nSerial = 80, 
  m_pAnchoredFlys = std::unique_ptr<std::__debug::vector<SwFrameFormat*,
std::allocator<SwFrameFormat*> >> containing 0x0, m_pStartOfSection =
0x55555bebad60}

Here's the test which fails:
   1507     // anchor only to paragraphs, or start nodes in case of
RndStdIds::FLY_AT_FLY
   1508     // also allow table node, this is used when a table is selected and
is converted to a frame by the UI
   1509     assert(!pPos
   1510             || ((RndStdIds::FLY_AT_FLY == nAnchorId) &&
   1511                     dynamic_cast<SwStartNode*>(&pPos->nNode.GetNode()))
   1512             || (RndStdIds::FLY_AT_PARA == nAnchorId &&
dynamic_cast<SwTableNode*>(&pPos->nNode.GetNode()))
   1513             || dynamic_cast<SwTextNode*>(&pPos->nNode.GetNode()));

Michael: noticing

thought you might have some idea here.
