I use Erlang OTP r16b02 with odbc-2.10.17, unixODBC 2.3.1, Oracle Client 11.2.3 on the Red Hat Enterprise Linux Server 6.3 x86_64.

And I get some glibc error messages:

*** glibc detected *** /home/user/app1/lib/odbc-2.10.17/priv/bin/odbcserver: free(): invalid next size (fast): 0x0000000002192490 ***

*** glibc detected *** /home/user/app1/lib/odbc-2.10.17/priv/bin/odbcserver: corrupted double-linked list: 0x00000000013d7110 ***



Often odbcserver crashes...

Is it known bug?

It's looks like odbcserver has invalid memory usage code and r17.3 has no significant changes in the odbc.
