Same problem on OpenSUSE 11.0 x64.
Try some valgrind / gdb pass to identify the problem

Hi,

2008/7/31 Anonymous :

I've tried to compile ruby 1.9 svn HEAD on an openSUSE 11.0 and ran into a build problem with prelude.c Build log is attached.

I duplicated the problem on openSUSE 11.0 on VMware on 32bit WindowsXP.

To simplify it, multiple assignment dumps core.

$ ./miniruby -e 'a, b = 1, 2'

Aborted

The cause is, the function REMOVE_ELEM in compile.c is certainly called
but seems not to work. I think gcc does wrong optimization because:

  • if building with optflags="-O0", it works
  • if adding attribute((noinline)) to REMOVE_ELEM, it works
  • if building with gcc 4.3.1 built by myself, it works

So I suspect packaging issue of gcc in openSUSE 11.0 or gcc's own bug.
As a workaround, you may use ./configure optflags="-O0".
