I should fix by mozctl19.dll of x64 version

Blocks: 471090
Status: UNCONFIRMED → NEW
Ever confirmed: true
Hardware: x86 → x86_64
That would fix the --enable-jemalloc case, but not the default build. (Our nightlies do ship with --enable-jemalloc, FWIW)

Tinderbox build uses VC++2010 now and Microsoft provides the hotfix for this issue.
Reporter should use their hotfix.  So I mark as WONTFIX.

If tinderbox build use VC++2005, I will reconsider this.
