[MacRuby-devel] malloc: resurrection error

[Laurent Sansonetti]

Hi Conrad,

I don't think anyone reproduced that problem so far. This is  
interesting. First, did you try building a fresh copy of trunk? (doing  
a rake clean).

If yes, it would be nice to debug this. Could you do the following in  
a terminal:

$ DYLD_LIBRARY_PATH=. gdb --args ./macruby -I./lib mspec/bin/mspec-ci - 
B spec/macruby.mspec :full
[... inside gdb]
(gdb) b auto_zone_resurrection_error
(gdb) r
[... macruby will run and yield once it hits the breakpoint...]
(gdb) thread all apply bt

Copy/paste the output of the last command to us :)

Thanks in advance,
Laurent
