Before the error, I got tens of thousands of warnings like this:

Here is my parameters for the demo configuration, tcl & matlab are in PATH so I do not specify them.

$ ./configure --with-sptk-search-path=/usr/local/SPTK-3.3/bin --with-hts-search-path=/usr/local/hts-2.1.1/bin --with-hts-engine-search-path=/usr/local/hts_engine_API-1.03/bin --with-openfst-search-path=/usr/local/openfst-1.1/bin --with-straight-path=/usr/local/STRAIGHTV40_007c



Here is my parameters for the hts-2.1.1 configuration

$ ./configure SMAX=11 PAT_LEN=8192 --prefix=/usr/local/hts-2.1.1 CC=icc CXX=icpc



Here is my icc version

$ icc -V

My questions are:
1. Why this error occurred? Is this error a bug?
2. Is the Warings and iteration changes normal? I did not find this kind of messages in the same section of the non-straight demo log file.




the orignal log file is attached.
