Hello,
I'm working with the php-v8js module[1] and I'm getting occasional,
but repeatable crashes in v8::Context::New. I'm positive that there's
something wrong with the way the module is implemented... but I'm not
sure what is wrong.
I'm using V8 3.2.8.2 on x86_64 (tried both with snapshot on and off,
debug and release builds).
My backtrace is like this (same every time):
Program received signal SIGABRT, Aborted.
0x00007f0164e819a5 in raise (sig=6) at ../nptl/sysdeps/unix/sysv/linux/
raise.c:64
64 return INLINE_SYSCALL (tgkill, 3, pid, selftid, sig);

Does anyone here have any tips what kind of error should I be looking
for?
