[AsteriskBrasil] Asterisk crash em SQLNumResultCols () from /usr/lib/libodbc.so.1

[Matheus Rossato]

Prezados,

   Recentemente enviei um e-mail sobre crash no servidor asterisk que atua
como proxy, agora estou postando um crash que ocorre nos gateways asterisk
que possuem o odbc e o freetds. Os gateways fazem a conexão com a pública e
gravam as ligações, após inserem no banco MSSQL2K através do odbc os dados
da ligação e o nome do arquivo gerado. Abaixo segue o backtrace de uma
queda. Se alguém souber alguma coisa que possa ajudar, agradeço.

Abraços
Matheus Rossato
