happen after I imported a "P1719" corpus, if I empty TXM corpora and let only the "P1719" corpus. There is no buffer overflow.

Solution 1¶

it seems that the bug is provoked when the registry path argument is too long or when there is too much loaded corpus.

Find the buffer that fails and change its size.

Validation tests¶

SJ: need more precisions about the validation tests but OK here (Win 7 x64) with this long param command line: Starting NullSearchEngineServer: [C:\Tools\Textometrie\TXM\TXM_0.7.8_64bit\TXM\plugins\CWBInstaller_1.0.0.201604041021\res\win64\cqpserver.exe, -I, C:\Tools\Textometrie\TXM\TXM_0.7.8_64bit\TXM\plugins\CWBInstaller_1.0.0.201604041021\res\cqpserver.init, -r, C:\Users\s\TXM\corpora\graal\registry;C:\Users\s\TXM\corpora\VOEUX\registry;C:\Users\s\TXM\corpora\ANNOTATION\registry;C:\Users\s\TXM\corpora\brown\registry;C:\Users\s\TXM\corpora\CORPUSESTOUT\registry;C:\Users\s\TXM\corpora\discours-back\registry;C:\Users\s\TXM\corpora\EDITONODD\registry;C:\Users\s\TXM\corpora\LIVRETOPERA\registry;C:\Users\s\TXM\corpora\LIVRETSOPERA\registry;C:\Users\s\TXM\corpora\LIVRETSOPERAORIGINAL\registry;C:\Users\s\TXM\corpora\OPERANORMAL\registry;C:\Users\s\TXM\corpora\OPERATESTS\registry;C:\Users\s\TXM\corpora\PARTHA\registry;C:\Users\s\TXM\corpora\PERFS1\registry;C:\Users\s\TXM\corpora\PERFS3\registry;C:\Users\s\TXM\corpora\PERFS4\registry;C:\Users\s\TXM\corpora\PERFS5\registry;C:\Users\s\TXM\corpora\PERFS50\registry;C:\Users\s\TXM\corpora\PERFS6\registry;C:\Users\s\TXM\corpora\PERFS7\registry;C:\Users\s\TXM\corpora\PERFS8\registry;C:\Users\s\TXM\corpora\pressepapier4\registry;C:\Users\s\TXM\corpora\rcorpora\registry;C:\Users\s\TXM\corpora\TESTBUGIMPORTCHINOIS14\registry;C:\Users\s\TXM\corpora\TESTBUGIMPORTCHINOIS16\registry;C:\Users\s\TXM\corpora\TESTBUGIMPORTCHINOIS4_temp\registry;C:\Users\s\TXM\corpora\TESTVI\registry;C:\Users\s\TXM\corpora\TESTVI2\registry, -b, 1000000, -d, OFF, -P, 4877]
