Subject: Work around MSVC's lack of support for unrestricted unions by making this
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=402e84934bdb2b5da17762df1e2a36aded207778;p=clang

Work around MSVC's lack of support for unrestricted unions by making this
struct a bit bigger under MSVC (this shouldn't be a big deal; we typically
allocate no more than two of these at a time, on the stack).
