Someone else has it too (https://bugs.winehq.org/show_bug.cgi?id=41086#c11)
Still present for me with wine-1.9.19-168-g2035a8c.
I can't confirm the regression test.
I reverted commits one-by-one up to (not including): Commit: dd6b7239c997bd56a8b64c0b4400e60fdbbc0bfb Author: Piotr Caban <piotr at codeweavers.com> Date: Tue Sep 27 09:33:12 2016 +0200 msvcp140: Add codecvt<wchar_t,char,_Mbstatet> exports. and the application crashed each time with the backtrace from this bug.
There is no crash when WINEDEBUG=warn+heap is in effect.
With dd6b723..42cfb0a^, the crash is due to msvcp140.dll._Cnd_destroy_in_situ not being implemented (yet): that's another issue/crash
