Description

This lines cause crashing (bug already tracked in CoCoALib)

For I := 1 To 2 Do
  PrintLn I;
  P ::= QQ[x,y,z];
  phi := CoeffEmbeddingHom(P);
EndFor;

It crashes only when creating the ringhoms in a rapid succession.
This issue is just to remind me that, when fixed, I should add this to the cocoa-5 tests.
