[libvoikko] Strange bug in the interface between hfst-ospell and libvoikko

[Sjur Moshagen]

Hello,

The following bug has me puzzled:

$ voikkospell -l -p tools/spellcheckers/fstbased/hfst/
libc++abi.dylib: terminating with uncaught exception of type hfst_ol::ZHfstMetaDataParsingError
Abort trap: 6

When reading the same file using hfst-ospell in verbose mode (to force it to read, parse and print the metadata), there are no problems:

$ hfst-ospell -v tools/spellcheckers/fstbased/hfst/smn.zhfst 
Following metadata was read from ZHFST archive:
