handling out paramters stopped working

[hmmftg]

Hi
First of all, thanks for great driver
recently after I uopdated my project to emulate and check broken-pipe problem, new compiled binary gets:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small

When I try to execute out-paramater example I also get this error:

Connection string:  oracle://user:pass@server:poer/?SID=sid&TRACE FILE=oracle_trace.log
Finish create table GOORA_TEMP_VISIT : 1.028699205s
100 rows inserted:  1.525866289s
Can't get output parameters ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at line 2

Finish drop table:  67.15662ms

in my oracle_trace file:

[hmmftg]

I've tried previous versions, this issue happens after version 2.5.4 and with previous versions this problem did not happened

[hmmftg]

un-commenting

par.MaxCharLen = len([]rune(value))

in file parameter_encode.go did fix the issue

[sijms]

I will investigate the issue and find a solution
