Seems like absence of python and opt in PATH was the problem here:

/usr/home/kparzysz/bld.lv/Release+Asserts/bin/bugpoint -load 
/usr/home/kparzysz/bld.lv/Release+Asserts/lib/BugpointPasses.so 
--compile-custom 
--compile-command="/usr/home/kparzysz/llvm/test/BugPoint/compile-custom.ll.py 
arg1 arg2" --output-prefix 
/usr/home/kparzysz/bld.lv/test/BugPoint/Output/compile-custom.ll.tmp

After adding both to PATH:


/usr/home/kparzysz/bld.lv/Release+Asserts/bin/bugpoint -load 
/usr/home/kparzysz/bld.lv/Release+Asserts/lib/BugpointPasses.so 
--compile-custom 
--compile-command="/usr/home/kparzysz/llvm/test/BugPoint/compile-custom.ll.py

/usr/home/kparzysz/bld.lv/test/BugPoint/Output/compile-custom.ll.tmp

With piping through FileCheck, I get

<crash>
but the return code is 0.
