--- Comment #1 from G. Steinmetz <gscfq@t-online.de> ---
Some cases with small numbers :
$ cat zz1.f90
program p
character :: c = 'c'
integer :: i = -1
c = 'abc'(i:i)
print *, c
end
$ cat zz2.f90
program p
character :: c = 'c'
integer :: i = -123
c = 'abc'(i:i)
print *, c
end
$ gfortran-11-20210221 zz1.f90 -O2 && ./a.out
$ gfortran-11-20210221 zz2.f90 -O2 && ./a.out
c
---
The value at which the switchover from no-ICE to ICE occurs
depends on used options, and changes with gfortran versions
and environment, e.g.
$ cat za.f90 # no-ICE
program p
character :: c
integer :: i = -1800000
c = 'abc'(i:i)
print *, c
end
$ cat zb.f90 # ICE
program p
character :: c
integer :: i = -1900000
c = 'abc'(i:i)
print *, c
end

Strange, for me the ICE is reproducible on different machines
and also on https://godbolt.org/ (!) -- always with -O2.

The issue really depends on optimization.
Confirmed for all tested -O greater than -O0: -Og, -O, -Os, -O2, -O3.
It disappears when declaring i volatile, as in
integer, volatile :: i = -12345678

fold-const: Fix ICE in fold_read_from_constant_string on invalid code
[PR99204]
fold_read_from_constant_string and expand_expr_real_1 have code to optimize
constant reads from string (tree vs. rtl).
If the STRING_CST array type has zero low bound, index is fold converted to
sizetype and so the compare_tree_int works fine, but if it has some other
low bound, it calls size_diffop_loc and that function from 2 sizetype
operands creates a ssizetype difference. expand_expr_real_1 then uses
tree_fits_uhwi_p + compare_tree_int and so works fine, but fold-const.c
only checked if index is INTEGER_CST and calls compare_tree_int, which
means
for negative index it will succeed and result in UB in the compiler.

fold-const: Fix ICE in fold_read_from_constant_string on invalid code
[PR99204]
fold_read_from_constant_string and expand_expr_real_1 have code to optimize
constant reads from string (tree vs. rtl).
If the STRING_CST array type has zero low bound, index is fold converted to
sizetype and so the compare_tree_int works fine, but if it has some other
low bound, it calls size_diffop_loc and that function from 2 sizetype
operands creates a ssizetype difference. expand_expr_real_1 then uses
tree_fits_uhwi_p + compare_tree_int and so works fine, but fold-const.c
only checked if index is INTEGER_CST and calls compare_tree_int, which
means
for negative index it will succeed and result in UB in the compiler.

* fold-const.c (fold_read_from_constant_string): Check that
tree_fits_uhwi_p (index) rather than just that index is
INTEGER_CST.
* gfortran.dg/pr99204.f90: New test.
