Assertion failure in fstmakecontextsyms utility

[ghost]

The usage example provided in the code comment at fstmakecontextsym.cc doesn't work giving an assertion failure:

$ fstmakecontextsyms phones.txt ilabels.int > context_syms.txt
fstmakecontextsyms phones.txt ilabels.int
ASSERTION_FAILED (fstmakecontextsyms[5.5.246-7a1908]:CreateILabelInfoSymbolTable():context-fst.cc:348) Assertion failed: (!info.empty() && !info[0].empty())

[ Stack-Trace: ]
kaldi::MessageLogger::LogMessage() const
kaldi::KaldiAssertFailure_(char const*, char const*, int, char const*)
fst::CreateILabelInfoSymbolTable(std::vector<std::vector<int, std::allocator<int> >, std::allocator<std::vector<int, std::allocator<int> > > > const&, fst::SymbolTable const&, std::string, std::string)
main
__libc_start_main
fstmakecontextsyms() [0x4034e9]

Aborted

OTH, according the online documentation, the first item of the ilabel_info object is supposed to be an empty vector. Just inverting the check !info[0].empty() seems to fix the issue. Here is the commit in my branch for the reference https://github.com/dorozhkin-stc/kaldi/commit/0afbadb25883f0f46f2f05dcb54f9d142e5e9d3e.

Can you please make a PR for that?
We don't often run that code so I guess I can just about believe this was a bug (although I'm surprised it was never encountered before).

sorry, my mouse is acting up.

OK, this is my PR: #3142

but I guess this is not my fault.

no, it's not your fault. that's coming from a compilation of different stuff. y.
