I'm testing with the example function:
create function sum_args (

external name 'udrcpp_example!sum_args'
engine udr;
select sum_args(1, 2, 3) from rdb$database where 1 = 0;
I put breakpoint in UdrEngine.cpp here:
~SharedFunction()
{
engine->deleteChildren(children);
}
And engine calls it.
Can you do the same test using sum_args?
I just tried it with v3 and it doesn't call nor ~SharedFunction(), nor
ExtEngineManager::Function::~Function(), nor Jrd::Routine::~Routine().
Than I found that it was fixed in v4 with PR168 but never backported into v3.
What was not fixed and still leaks memory in v4 - is few metadata instances
incorrectly counted at ExtEngineManager::makeFunction() and
ExtEngineManager::makeProcedure().
Fix is committed into v4.0-release. Jiří could you try next build and report
here ?
