<pre>When trying to use the Clang Python bindings inside bpython, every time I
loaded a TranslationUnit from source, bpython segfaulted.
I've found the problem to be in
llvm::sys::Process::FileDescriptorHasColors(int). It uses terminfo to check if
the file descriptor has colors, but instead of restoring the `cur_term`
variable to its original value, it sets it to NULL. When control returns to the
NCurses app (bpython), it crashes because no current terminal is set.
This is the first time I ever deal with LLVM or NCurses code, so I might be
wrong. I did a search to see if this had been reported before, but I didn't
find anything.
To reproduce, fire up bpython and enter:
import clang.cindex
clang.cindex.TranslationUnit.from_source("path to some C file")
You need the Clang Python bindings installed, of course.</pre>
