It is a this cyclic definition in
/usr/lib/debug/usr/bin/containerd-stress-1.6.6-4.fc36.x86_64.debug

 [112f71]    subroutine_type      abbrev: 48
             name                 (string) "text/template/parse.stateFn"

               type                 (ref_addr) [112dff]

 [112fa3]    typedef              abbrev: 47
             name                 (string) "text/template/parse.stateFn"
             type                 (ref_addr) [112f71]
 [112fc4]    pointer_type         abbrev: 50
             name                 (string) "*text/template/parse.stateFn"
             type                 (ref_addr) [112fa3]
             lo_user+0x900        (data1) 0
             lo_user+0x904        (addr) +0x0000000000057cc0

So the subroutine has one argument which is a pointer to a typedef for the
subroutine itself.

This causes a stack overflow in die_pretty_print_type trying to create a st=
ring
representation for that subroutine.
