I have upgraded to glibc version 2.15-r2. 

Before the upgrade the error was 

/usr/lib/ruby/site_ruby/1.8/wx/classes/app.rb:16: [BUG] Segmentation
fault ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]

after the upgrade it changes to this.

/usr/lib/ruby/site_ruby/1.8/i686-linux/wxruby2.so: [BUG] Segmentation
fault ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]

But the stanges thing happens. If I run it via gdb it works fine !!!,
no Segmentation fault.

Do you need "set solib-search-path" or "set sysroot"?

And the same problem for every GUI program I have tested on my system. 

like firefox, claws mail

But it complains about:  "set solib-search-path" or "set sysroot"?
