Gcc 2.96 has no problem with #ident directive in the file.

Haven't checked if GCC 3.4 itself has deprecated this directive though...

I'm not familiar with #ident, can you please provide a testcase?  Have you tried
#pragma ident?

Here's a testcase:

----
#ident "foo"
----

$ llvmgcc -S test.c 
test.c:-77: internal compiler error: Segmentation fault
Please submit a full bug report,

That is pretty catastrophic.  I'll look into it.

Ok, the bug has been fixed in the mainline C front-end.  Here's a patch:

If you're not interested in rebuilding the C frontend, you can pass '-fno-ident'
on the llvmgcc command line to work around this problem.  Thanks for the great
bug report!

For the record, this is tested as: test/Regression/CFrontend/2003-10-28-ident.c
