Daniel,

Does this also disappear, like 31550, with versions earlier than 20070318?

Yes, I observed both crashes (PR31550, PR31331) after the update from 20070308
to 20070412. I can try intermediate versions if this would help?

On a different host, 20070316 works as well.

Daniel reports that the patch for PR31550 has fixed this one too.

Thanks for the reports , Daniel.  As usual, they were testing.

This fix commited for PR31550 fixes this ICE as well. Closing as dupe.

I am seeing 

internal compiler error: in fold_convert, at fold-const.c:2330

using gcc version 4.3.0 20070417 (experimental)

If I follow the thread in this bug list, it seems that this version should have
the patch applied.  So I am not sure if I am not testing a patched version or
if there is still an ICE there.  FWIW, this code used to compile just fine with
gfortran up until a month ago.  

Sadly, I can't seem to distill this down into a simple test case.


gfortran  -Jt/Linux.gfortran.debug/m -I t/Linux.gfortran.debug/m -g

with preprocessed source if appropriate.

That's right. Daniel, could you confirm that your testcase is indeed fixed with
today's mainline?

> Sadly, I can't seem to distill this down into a simple test case.

Even if it's not that small, could you send it to my privately? (fxcoudert at
gcc dot gnu dot org)
Make a tarball of the source file and instructions on how to build it, and I'll
reduce it.

Confirmed, no more crashes in my code.

Thanks for the help.  I'll put together a tarball and pass it to you privately
as instructed.
