Hi,

I found problematic file in libdirac package which don't want to compile with
GCC 4.5.0 (20090827), but compiles fine with GCC 4.4.2 (20090825).

The problematic file is "libdirac_common/common.cpp". I include preprocessed
file.

$ make_68k_v45

------- Comment #5 from foom at fuhm dot net  2009-10-30 02:42 -------
An error very much like this is also causing a bunch of files in my program to
fail to compile with 4.5 with -O1 and above. I was unable to reduce a simple
test case from my (private) code, though: many changes that seem like they
should be unrelated cause the bug to go away. So I really hope my bug is
actually the same thing as this already-somewhat-reduced test case. :)

I'm using the ubuntu gcc-snapshot 20091018 package, on x86-64.

The error message is a little bit different, so I'm including it below, just in
case you might think it indicates a different underlying cause.

Unfortunately the problem still persists, see following testcase
which crashes in the same fashion when compiled with "-O3 -m32"
on x86_64-unknown-linux-gnu.

Confirmed.  It passes if I add -fno-ipa-cp, maybe martin can have a look.

------- Comment #13 from foom at fuhm dot net  2010-01-12 06:27 -------
The crash is still present for my code. I'm using:
g++ (Debian 20091228-2) 4.5.0 20091228 (experimental) [trunk revision 155486]
on AMD64.

Passing -fno-ipa-cp also makes the bug disappear for me. But apparently r154673
did not fix the underlying issue, only make it unreproducible with the test
case here. I can try again to minimize, but I'm not optimistic: this bug seems
to appear and disappear almost randomly with minor adjustments to the code, and
unfortunately I cannot post my complete code.

------- Comment #15 from foom at fuhm dot net  2010-02-10 23:24 -------
Nope, adding -fno-indirect-inlining has no effect.

I'm now using:
g++-4.5 (Debian 4.5-20100202-1) 4.5.0 20100202 (experimental) [trunk revision
156452]

Problem still occurs, -fno-ipa-cp still makes it go away.

Patch making call statement redirection based on cgraph edges clearer

You may (or may not) be seeing an issue that I ran into when working
on devirtualization.  The attached patch should address it.  Can you
please try to compile your source with a patched gcc and see whthr it
helps?  If so, I'll try to push this change to 4.5.  If not, I'll keep
it for 4.6. Thanks.

------- Comment #18 from foom at fuhm dot net  2010-03-10 20:32 -------
Sorry for the extreme delay in responding. I can confirm that applying that
patch on top of:
gcc-4.5 (Debian 4.5-20100227-1) 4.5.0 20100227 (experimental) [trunk revision
157109]
*does* make my issue go away, and my program compile correctly without
requiring the -fno-ipa-cp argument.

Thank you. 
Should this report be reopened for that patch to be applied? I don't have the
reopen option.

Good to hear that.  I don't think there is a need to reopen the bug since it is
most probably a duplicate of PR 42450 which has a testcase and is being dealt
with.

Thanks for testing, though.
