Preprocessed sample code (gzip compressed)
I am compiling C++ code with the clang target "i686-pc-windows-msvc" and the
SDK from VS 2013. When compiling with the arguments "-g" and "-D_DLL", I get an
assertion error for most of my code files. Without -g or without -g, the code
is compiled successfully.
It is reproducible with the attached preprocessed code and the following
commmand line:
clang++ -target i686-pc-windows-msvc Deserialiser.i -c -g -o Deserialiser.o
The assertion message below is generated by Clang 3.5.0 from the official Win32
installer. I have also built a Cygwin version of Clang 3.5.0 (the attached
preprocessed source is generated with the Cygwin build), and I am getting
another message.
Error message from Clang 3.5.0 from the official Win32 installer:
