cellminer.rb:136: [BUG] Segmentation fault

I get segfault and I do have /spu mounted and I use ruby 1.9.2p180 with YDL.

build log: http://pastebin.com/Ds2SN6WH

How can I trace it?

Since the problem occurs within spe_program_load(), it seems there is something wrong with the embedded SPU code.

The immediate problem appears to stem from this warning:

/usr/bin/ld: warning: powerpc:common64 architecture of input file `spu_worker.o' is incompatible with powerpc:common output

You could solve this by arranging to pass the -m32 flag to ppu-embedspu in ext/depend like so:

spu_worker.o: spu/worker.elf
        ppu-embedspu -m32 spu_worker $< $@

However, it looks like you may end up with another problem which is that the PPU miner is being built as 64-bit with ppu-gcc but the Ruby glue code is built as 32-bit with gcc. Probably you will want to compile everything with one or the other, or pass appropriate flags to end up with the same output format in any case.

I do not have access to the ps3 now and I can't check it. I will come back to this later.
