Hi guys,
I have a trouble while trying to initialize v8::Context on x64 machine (
under i32 works fine though ).
I use latest commits from master, trunk, 3.25 branches. All of them have
the same issue.
Built v8 with gyp and "make x64.debug library=shared"
My OS is Ubuntu 13.04 x64. Before I had 13.10 and also tried v8 under it
and got the same result.
Cpp file in attachment.
gdb`s backtrace:

Does anybody have the same issue?
