Hi, to reproduce the issue you can download the code I try to compile from home.dgrechka.net/filestore/for_external/util.lib <http://home.dgrechka.net/filestore/for_external/util.lib>
I compile it with "emcc -o util.js util.lib" and get " DEBUG root: LLVM => JS DEBUG root: emscript: llvm backend: C:/Program Files/Emscripten/clang/e1.34.1 _64bit\llc c:\users\dmitry\appdata\local\temp\tmp68f47c\tmp72kctf.bc -march=js - filetype=asm -o c:\users\dmitry\appdata\local\temp\emscripten_temp\tmp9eqkrf.4.j s -O2 %218 = va_arg i32* %4, i64 LLVM ERROR: 0 && "some i64 thing we can't legalize yet" DEBUG root: emscript: llvm backend took 0.029000043869 seconds " Thanks in advance for fixing the issue.
