The ICE is occurring in the assert below

        1101    tree
        1102    gfc_conv_string_tmp (gfc_se * se, tree type, tree len)
-       1103    {
        1104      tree var;
        1105      tree tmp;
        1106    
        1107      gcc_assert (TREE_TYPE (len) == gfc_charlen_type_node);
        1108    

so len appears to have an invalid type.

This was r150823, which seems to be working for me. 

However, I don't see why r150825 fails for Dominique then (r150824/25 are both
Ada-related).

------- Comment #5 from jv244 at cam dot ac dot uk  2009-08-20 12:07 -------
I went checking my logs in more detail. I believe revision 150854 is fine (so
sorry, my previous guess was wrong), while 150940 fails for me. That would
leave three more revs from the FE:

r150856 | domob | 2009-08-17 20:55:30 +0200 (Mon, 17 Aug 2009) | 14 lines

2009-08-17  Daniel Kraft  <d@domob.eu>

r150858 | pault | 2009-08-17 22:17:12 +0200 (Mon, 17 Aug 2009) | 13 lines

2008-08-17  Paul Thomas  <pault@gcc.gnu.org>

r150875 | janus | 2009-08-18 16:23:35 +0200 (Tue, 18 Aug 2009) | 16 lines

2009-08-18  Janus Weil  <janus@gcc.gnu.org>
            Paul Thomas  <pault@gcc.gnu.org>

but I don't dare to guess this time :-)

The revision numbers are those recorded when I did the update, they are only an
upper bound for the relevant changes (and I don't have more precise ones).

Awww, come on, don't be shy ;)

Seriously, though, I'd bet that r150875 is not the culprit. Not because it's
mine, but because it is completely unrelated to CHARACTER.

I just tried r150875, which also works on my machine (unless I messed something
up). This means that the three guys above are all fine.

Maybe r150934?

Indeed: I just verified that r150934 is the source of this regression.
