------- Comment #3 from paul dot richard dot thomas at cea dot fr 2006-05-10 12:59 -------
I think that it is not correct to emit an ICE on this one. The patch below
emits an error and bails out.
I will submit in the next 24hours.

Apparently ignoring the ICE is given the thumbs down. See today's list.

------- Comment #7 from jvdelisle at gcc dot gnu dot org 2006-10-22 00:09 -------
Created an attachment (id=12472)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=12472&action=view)
A prelimary patch as one concept for handling this
This patch gives a good result for error messages. However we are still left
with some memory leak. I will have to explore this some more. The concept is
to reset the locus and then return the correct end statement after emitting the
error message. Whats nice about this is it gives errors for all the nested
statements missing the correct "END"
Comments anyone?

Confirmed. Here's an even shorter testcase:
