Hello,

I’m compiling Ruby 1.9 from the SVN tree, latest changeset is 12384 on  
OS  
X/PPC 10.4.9.

It fails during compilation with the following message:

## … gcc -O -pipe -pipe -fno-common -L. main.o libruby-static.a -lpthread -ldl -lobjc -o miniruby : – stack frame ------------ 0000 (0x126000): 00000000 \<- lfp \<- dfp – control frame ---------- c:0001 p:---- s:0001 b:-001 l:000000 d:000000 ------

[BUG] Bus Error  
ruby 1.9.0 (2007-05-25) [powerpc-darwin8.9.0]

Running miniruby and pressing ^D leads to the same message. miniruby -v,  
same.

Am I the only one? I’ve tried make clean, rerunning configure, changing  
-O2  
into -O, no success.

Thanks.

It’s a known bug.

My guess is that it is miniruby which fails.

Is it committed in trunk?

Any news on the bug where trying to use “-r debug” does not work because  
a hook is not yet available (according to ko1)? I can not switch (and  
therefore test) 1.9 is the debugger is not usable…

Thanks.

Yes, obviously. What I asked is what miniruby was about to do.

I think the very first invocation of miniruby during the compilation  
process is failling.

The compilation still faisl with the bus error but as for miniruby -v:

Now, it is just looping away, eating CPU cycles ☹

I have to kill it in another window. It is a plain 1.9 at changeset  
#12515.

As soon as I get a working ruby, I’ll test it, thanks.

Interestingly enough, the same sources on an Intel Mac (MBP) does not  
dump core.

This happens on the macbook pro as well though.
