Dear colleagues!
I need to create my own aggregate UDF, so I decided to test UDF_example
from Windows MySQL source.
I've created udf_example.dll and udf_example.lib with VC++ 6.0.
Then, I haven't any problem with all of udf's, excepting the aggregate
udf avgcost.
On my "SELECT avgcost(a,b) from t1;" Mysqld-max sends info message:
(Sorry, I try to translate from Russian)"
"the programm made fatal operation and will be closed".
On click the button "info" on this message I have next text (I try to
translate from Russian):
The programm MYSQLD-MAX called error on access to memory page
in module <no data> at address 00de:00000003.
Программа MYSQLD-MAX вызвала сбой при обращении к странице памяти
в модуле <нет данных> по адресу 00de:00000003.
