[Bug fortran/32472] New: ICE in trans-const.c:106 for REPEAT initialization expression of non-parameter

[burnus at gcc dot gnu dot org]

r.f90:1: internal compiler error: in gfc_conv_string_init, at
fortran/trans-const.c:106
(4.3.0 20070623, x86_64-unknown-linux-gnu)

This is
  gcc_assert (expr->expr_type == EXPR_CONSTANT);

Test case:
CHARACTER(len=1025) :: string2 = repeat('?',1025)
print *, string2
end

If one uses PARAMETER or a separate line (i.e. no initialization expression)
then it works.

I think this is parsed as a statement function. 
For something similar, I once got messages as: expected character but got
procedure. 

Couldn't find time to investigate further, though :(

(In reply to comment #1)

It's wierd - this works fine:

Character(1), parameter :: query = "?"
CHARACTER(len=1025) :: string2 = repeat(query,1025)
print *, string2
end

I have a fix for this that needs a bit of cleaning up - will submit tonight.

For some reason, gfc_simplify_repeat denies even the possibility of character
literal arguments - it's not even a question of a failing attempt to deal with
them:-)

OK - the patch did not regtest but the principle is established:  I know how to
fix it and need to get the details of the interface to existing code right.

This, I seem to think is.... well, fixed on trunk.

Thanks for the report, Tibias.
