[v8-users] OOM in Heap::ReserveSpace
Hi, I'm in the process of trying to upgrade from v8 6.0.186 to 6.7.288.46. In heap.cc, the latter now has a check for !deserialization_complete_ before throwing an OOM error. For some reason, my code can create one Isolate just fine, but if I try to create another, I run into the error. The comments in heap.cc suggest a low max old space size as a possible reason, but my code uses all defaults for heap initial values and everything worked fine on the previous v8 version, so that seems unlikely to be the culprit. What other possible cases could result in deserialization_complete_ being false at this point? Or maybe perform_gc is getting set when it's not supposed to be? Stack trace, not sure if it helps much though: <--- Last few GCs ---> <--- JS stacktrace ---> # # Fatal process OOM in insufficient memory to create an Isolate # Thread 12 "threadname" received signal SIGILL, Illegal instruction.

[v8-users] Re: Building V8 on Windows with Visual Studio 2017
Oh and I've tried running: *gclient sync *from my v8 directory: C:\Dev\common\v8>gclient sync C:\Dev\common\.gclient_entries missing, .gclient file in parent directory C:\Dev\common might not be the file you want to use. and it doesn't seem to bring down *third_party/llvm-build* Should it?? What am I missing? -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.

[v8-users] Building V8 on Windows with Visual Studio 2017
I'm trying to build V8 as a static library using Visual Studio 2017 (apparently 2017 is now required). I've done it in the past with VC 2015 successfully. After setting many environment variables and paths and following all the instructions multiple times it still won't work. I've got this in my PATH: C:\utility\depot_tools;C:\Utility\depot_tools\win_tools-2_7_6_bin\python\bin\ And these variables set: DEPOT_TOOLS_WIN_TOOLCHAIN = 0 GYP_MSVS_OVERRIDE_PATH = C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional GYP_MSVS_VERSION = 2017 WINDOWSSDKDIR = C:\Program Files (x86)\Windows Kits\10 My args.gn file contains this: is_debug = false target_cpu = "x64" is_component_build = false v8_static_library = true I think the build process seems to be looking for this: *../../third_party/llvm-build/Release+Asserts/bin/clang-cl.exe* Which was not installed, and I don't have. See build errors below. This repeats quite a few times for different .obj files.
