 The only difference between the files is the comment char # in line 1!

 BTW, thanks for implementing the long awaited backtrace, great job!

[MacRuby-devel] How can I catch segment faults?

2009-09-20 Thread B. Ohr (dev) 


Hey, after installing r2590 with backtrace support (thanks for that!)  
now I have the problem to catch segment faults.


It seems to be a problem inside of a hash#each_pair, but I have  
absolutely no idea where, and because it is foreign code a file name  
and line number would be more than useful!

Re: [MacRuby-devel] How can I catch segment faults?

2009-09-20 Thread Laurent Sansonetti 

Hi,

We will implement dwarf symbolication which will allow you to see the  
ruby method, filename and line instead of ?? in the gdb backtrace, but  
in the meantime an easy way to debug these problems is to toggle the  
ROXOR_VM_DEBUG variable to 1 in vm.cpp and recompile miniruby.


This will print a lot of information on stdout, which should allow you  
to track and identify the crash.


# Segmentation faults are bugs in MacRuby core, so in theory users  
should not see them :)


Also, try setting the GC_DISABLE environment variable to 1 before  
starting the program, if it doesn't crash then it's very likely a  
missing write barrier in the collector.

 Thanks for the report.

 This is not a problem in the AOT compiler. (Since last night, macirb is
 100% compiled post installation).
