   When compiling from master, I get the following warning using GCC 10.2.1

   0txmempool.cpp: In member function ‘CTxMemPool::setEntries CTxMemPool::GetIterSet(const std::set<uint256>&) const’:
   1txmempool.cpp:894:29: warning: ‘<anonymous>’ may be used uninitialized in this function [-Wmaybe-uninitialized]
   2  894 |     return Optional<txiter>{};
   3      |                             ^
   

   System: OS: Debian Buster Compiler: GCC 10.2.1

   Steps to reproduce:

   • grab master
   • go through the compilation process
   • get -Wmaybe-uninitialized compiler warning

   Thanks, however this is a false positive. See #20797, #20950, #20894.
