I've been trying to track down an build failure that I was pretty sure
came about from some patches I've been trying to merge, but I've now
reduced things to a bare unmodified tree and it's still failing. I
could have sworn that it wasn't doing that until I started adding
things, though, so I'm posting about it here before I make a bug report
so y'all can tell me if I did something dumb.
Essentially, what's happening is that I've got a build tree configured
with --enable-checking=all, and the first time it tries to use xgcc to
compile something, it dies with an ICE. Here are the gory details:
* Build system: Debian stable, up-to-date, on an Intel P3 machine,
running in a VMWare virtual machine.
* I updated my build tree to version 121332.
* I reverted all changes in the tree by pulling a patch with "svn diff",
applying it with "patch -R", and then rerunning "svn diff" to confirm
that absolutely no differences from the svn mainline were found.
* I created a new empty directory, and ran the following "configure"
command in it: ../svn-source/configure --verbose
--prefix=/home/brooks/bin-callexpr-c --enable-checking=all
--disable-bootstrap --enable-languages=c
* Then, I ran make. It died with the following error, in what I believe
is the first time it tries to use the newly-created xgcc:

Any ideas? Is this just me?
If this is something reproducable, I'll file a PR in the morning.
Thanks much!
