--- Comment #16 from G. Steinmetz <gscfq@t-online.de> ---

Seems to be fully covered by pr103609 (gfc_sym_get_dummy_args).
(that began to give an ICE between 20200726 and 20200809)

For this case :
Status of gcc-11 changed between 20200726 (ok) and 20200809 (ICE)
too, and gcc-11 was fixed between 20211113 (ICE) and 20211211 (ok).
Primarily gcc-12 was fixed between 20211205 (ICE) and 20211212 (ok).

Last backtrace for pr105182.f90 is :

BTW, an almost complete variation run did not yield any 
additional problem cases, only replicated the already known 
bug groups around pr103507 and pr99036.
