Description
Hi,
I have a specific file that is parsed correctly when saved, but crashes irony-server when sent as unsaved content. This is the backtrace:
Program terminated with signal SIGSEGV, Segmentation fault.
#0 0x00007efdb0d6bffb in ?? () from /usr/local/llvm-3.6/lib/libclang.so.3.6

The problem seems to be in Command.cpp, line 265:
char nl;
std::cin.read(&nl, 1);
if (nl != '\n') {
std::clog << "error: missing newline for unsaved file content\n";
return 0;
}I have done some debugging and it seems that, for this specific file, when unsaved, the newline is never sent to the server. Or the server somehow loses it. I cannot explain why. Moreover, the server should not crash in this situation. I don't know if the backtrace is a hint as to why the input stream loses the newline.
The file only has ASCII characters. I also tried changing the Elisp code to send another character instead of a newline, but the end result is the same.
