I think this is a GC problem somewhere as I cannot (on a modified source though) 
bootstrap on powerpc-apple-darwin either:

Actually the failure I see on powerpc-apple-darwin was my bug in the code I added sorry. 
I do not see otherwise.  Oh by the way what is your stack limit?

stack limit was 8Mb. However, after 
limit stacksize 65536
and a clean make bootstrap it segfaults in the same place.

Joost,

Perhaps you are having memory hardware problems?  I've just bootstrapped today's
branch with the same GMP version and configure switches.  The branch is working
on several different architectures, as well.

I can't exclude that (didn't run memtest). I did bootstrap the compiler on
another machine (with the same packages installed according to our CO) and that
worked fine. On the other hand, it is perfectly reproducable, and would be the
first problem with the machine (nevertheless, will be replaced somewhere next week).

However, one difference between the machines is the amount of memory available
and the older CPU. Also, I've following limits.

 limit
cputime 	0:0-1
filesize 	4194303 kbytes
datasize 	4194303 kbytes
stacksize 	8192 kbytes     ! tried various sizes
coredumpsize 	4194303 kbytes
memoryuse 	4194303 kbytes
vmemoryuse 	4194303 kbytes
descriptors 	1024 
memorylocked 	4194303 kbytes
maxproc 	256 
openfiles 	1024 

and this is what free returns:
             total       used       free     shared    buffers     cached
Mem:        515260     509496       5764          0      29784     313396
-/+ buffers/cache:     166316     348944
Swap:      1052248      24500    1027748

I've tried once the offending command in gdb, but I'm not experienced enough to
get more info.

Let's see if I can reproduce it locally with a .i file.  I've got a
256Mb RAM P3 that should be smaller than your old machine.

Do the following:

     1. Cut and paste the compile command that gets the SEGV.
     2. Add the switches -v -save-temps.
     3. Attach the output you get.
     4. Attach the generated insn-extract.i to the PR.

I will try to reproduce the problem locally.

But this shows that the file compiled just fine.  And, indeed, the file
compiles with no errors on my old P3.

I need you to post the .i files that causes your machine to SEGV.


Diego.

Bootstrap succeeded on a 256Mb i686-pc-linux-gnu with the same configure
options.  Your system's memory is likely faulty.  Try running memtest on it.

Actually, I think I can reproduce this now.  While cleaning up tree-cfg.c, I ran
into this exact same SEGV.  We were going beyond the ends of a local array
inside tree-ssa-alias.c.

I'm testing a fix right now.  Joost, do you still have access to this machine?

:-) The poor old machine was just doing its job it seems. 
Yes, it is still around.

Good.  After I test the patch locally, I'll update the PR.  If you have
time, could you try to bootstrap once again on that box?

sure, but if it involves anything more complicated than ./contrib/gcc_update, I
might need detailed instructions ... (fool proof is clearly an inappropriate term).

It won't.  After I get a clean bootstrap locally, I will commit to the
branch.  You can then run gcc_update or get a source snapshot from
http://gcc.gnu.org/projects/tree-ssa/
