This bug appears on the second run of a command. I may be doing
something BFD/GDB considers sneaky. This script uses RubyInline
which compiles and dynamically links a shared library. Each run
removes the shared library forcing it to be rebuilt. Perhaps BFD
thinks the library hasn't changed and bad things happen?
Full trace:
