Example Source
I've cross-compiled libc++, libc++abi and libunwind (All release versions of
v3.8.1) with arm-linux-gnueabi-g++ v5.4.0 (as found on Ubuntu 16.04) to be
linked statically. I then continue to use it to compile and link my application
that throws and catches exceptions.
Running this application fails with:
Assertion failed: ttypeEncoding == DW_EH_PE_absptr && "Unexpected
TTypeEncoding" (/path/to/libcxxabi/src/cxa_personality.cpp: get_shim_type_info:
350)
I've attached an example application that should trigger this, as well as it's
assembly.</pre>
