run_torgue fails when compiling under windows (use_custom_libcxx=false)

[Thomas Liebmann]

Hi,

I'm trying to compile 8.8.278.14 under Windows and MSVC 2017 using the following flags:

gn gen out/x64-win.release --args="is_debug=false target_cpu=\"x64\" v8_target_cpu=\"x64\" use_goma=false is_clang=true v8_static_library=false is_component_build=true use_custom_libcxx=false v8_untrusted_code_mitigations=true"

Unfortunatly it fails on step run_torgue

[31/2673] ACTION //:run_torque(//build/toolchain/win:win_clang_x64)

...

Return code is C0000409

Any ideas are appreciated.

Update:

I tried to run torque in the debugger. It fails with:

Unhandled exception at 0x00007FFA38D9F7A0 (ntdll.dll) in torque.exe: RangeChecks instrumentation code detected an out of range array access.

One more update:

I've disabled the Control Flow Guard, now it's running without a crash.

(Maybe) Beginner question: "is_clang=true" means "not building with MS C++ Compiler" - right?

So i'm wondering if you want to build with MS C++ Compiler or CLang?

[Thomas Liebmann]

It means I'm compiling with clang, but using the MSVC-library (use_custom_libcxx=false).

Of couse my first choice would be using MSVC for everything (is_clang=false) but than I'm getting linker errors ...
