Subject: Disable RandomizedBaseAddress on MSVC builds
X-Git-Tag: REL9_3_4~35
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b88ecb002ef486ff76dd130fb0c6ac01551414dc;p=postgresql

Disable RandomizedBaseAddress on MSVC builds

The ASLR in Windows 8/Windows 2012 can break PostgreSQL's shared memory. It
doesn't fail every time (which is explained by the Random part in ASLR), but
can fail with errors abut failing to reserve shared memory region.
