Thank you for reporting a bug.

I can reproduce similar SEGV on "ruby 1.9.4dev (2011-09-30 trunk 33364) [i686-linux]"
The following patch seems fix this issue.

Narihiro-san, could you take a glance to this patch?

BTW, when GC parameters are set by environment variable, some messages are output to standard output with printf().
I wonder if these are statements for debug and should be eliminated. Can I delete them?

BTW, when GC parameters are set by environment variable, some messages are output to standard output with printf().
I wonder if these are statements for debug and should be eliminated. Can I delete them?

I think this behavior is specific.
Matz, What do you think?

I think this behavior is specific.

I think they should be shown only when GC_NOTIFY is set, at least.

Thank you for your comments.

I think shown with -w option is fine.
And I feel it's more natural the messages shown with -w are outputted to stderr.
I attach a patch with test.
If there's no opposite opinion, I'll check in it.
