nnet3-info occurs a segment fault. #2875
Description
Using kaldi latest (70aba21), I get the following error when running nnet3-info. (It happens during steps/nnet3/xconfig_to_configs.py)
$ nnet3-info exp/chain_rvb/tdnn1n_rvb/configs//ref.raw Segmentation fault (core dumped) src/nnet3/nnet-parse.cc:522 <- Infinite recursion occurs at this location.
The error is a side effect caused by #2496 and is associated with a commit of c362b2c.
The following changes are required.
