Wow!

A problem with aliases is that they are not inherited by child processes. Do
you think it could have negative side effects to globally

setenv LD_PRELOAD /opt/intel/compiler70/ia32/lib/libunwind.so.3

?

I doesn't seem to do any obvious harm. Did you come across any warnings while
reading the man pages?
