Complied using PHP 7.09, Visual Studio 2015 community edition from 64 bit Native tools command prompt. Able to create a dll file but fails while loading from Apache. When I start Apache from command prompt, I am getting the following errors thru VC 2015 debugger :

Unhandled exception at 0x00007FFB15E2E6FC (ntdll.dll) in httpd.exe: 0xC0000374: A heap has been corrupted (parameters: 0x00007FFB15E822B0).

That appears to be a duplicate of bug #69852. TL;DR: PECL/ibm_db2 is not yet fit for PHP 7.
