Hi Mark,

I have come up with a better solution for the problem with the Visual Studio 2010 compiler crashes.

[...]

I changed configure/os/CONFIG_SITE.Common.windows-x64-static as follows:

# 64-bit Visual Studio 2010 builds fail when built with the -GL optimization

# flag which is set in CONFIG.win32-x86.win32-x86 with these lines:

# OPT_CFLAGS_YES = -Ox -GL -Oy-

# OPT_CXXFLAGS_YES = -Ox -GL -Oy-

# The lines below have the -GL flag removed from OPT_CFLAGS_YES and OPT_CXXFLAGS_YES.

# If you are using a newer version of Visual Studio you can try removing these lines.

OPT_CFLAGS_YES   = -Ox -Oy-

OPT_CXXFLAGS_YES = -Ox -Oy-

My impression is that VS 2013 and 2015 do not have that issue. (For older versions, I only have access to the Express editions that do not contain 64bit compilers.)

Is there a way to determine the VS version during make, so that we could apply your suggested change only for specific VS versions that need it?

Cheers,
