HEAD built with msvc++ crashes on initdb. I'd appreciate any pointers as
to where to start looking...

Unhandled exception at 0x0046b9c7 in postgres.exe: 0xC0000005: Access
violation reading location 0x000006b3.

The crash is on the line:
        vac->relid = rel->rd_lockInfo.lockRelId;

in _bt_start_vacuum().

From what I can tell, the entire rel pointer is invalid at this point,
because the debugger says "Expression cannot be evaluated" for all
fields in it, including simple ints.
