[Patch, fortran] PR36463 Bad symbol '@0'

[Mikael Morin <mikael dot morin at tele2 dot fr>]

Hello,

this patch use the symbol's name instead of the symtree's when replacing
symtrees (they are different in case of module procedure dummy arguments).
It uses gfc_find_symtree instead of gfc_get_sym_tree as the latter used
to create a new symtree in case it didn't find it, which was making the
error difficult to track.


Regression tested on x86_64-unknown-linux-gnu. Ok for trunk?
Janus, I would like your review especially, as you wrote this part.

Mikael
