Yes, the debugger points me to a setlocale call, see below.

When lyx is compiled with ENABLE_NLS it uses in message.C
the LC_MESSAGES macro, which is not defined by msvc.
But in intl/libintl.h it is set to an dummy value:
/* The LC_MESSAGES locale category is the category used by the functions
gettext() and dgettext(). It is specified in POSIX, but not in ANSI C.
On systems that don't define it, use an arbitrary value instead.
On Solaris, <locale.h> defines __LOCALE_H (or _LOCALE_H in Solaris 2.5)
then includes <libintl.h> (i.e. this file!) and then only defines
LC_MESSAGES. To avoid a redefinition warning, don't define LC_MESSAGES
in this case. */
#if !defined LC_MESSAGES && !(defined __LOCALE_H || (defined _LOCALE_H &&
defined __sun))
# define LC_MESSAGES 1729
#endif
Using setlocal with an to msvc unknown value aborts immediately the program.
A first fix is to test on LC_MESSAGES and to
guard the call with HAVE_LC_MESSAGES:

In message.C there is already a disabled LC_MESSAGES-free code.
I've tried it but the std::message of msvc uses only 2 parameters.
