When trying to do this from terminal:
{{{
runtime_loader: /boot/system/lib/libstdc++.r4.so: Could not resolve symbol
'__ti9exception'
resolve symbol "__ti9exception" returned: -2147478780
runtime_loader: /boot/system/lib/libstdc++.r4.so: Troubles relocating:
Symbol not found
}}}
What happens is the LD_PRELOAD is inherited to child processes. In this
case, it seems the "Screenshot" app ends up being run with the gcc4
libroot_debug loaded, so it fails to run. We may want to at least catch
the error and display the error message in an alert.
This happens in kits/interface/Window.cpp , and Screenshot is run using
be_roster->Launch() by MIME signature. There is no error checking on the
return value.
One level deeper, I don't know if be_roster->Launch() should inherit the
LD_PRELOAD value from the environment.
