New issue 3545 by [email protected]: Frequent SEGV crashes in nodejs
https://code.google.com/p/v8/issues/detail?id=3545
I recently upgraded to node 0.10.31, and have started receiving an alarming
number of SEVGs from v8 (which is version 3.14.5.9 in this nodejs). My
nodejs is self-compiled, but I am using the official sources (i.e.
http://nodejs.org/dist/v0.10.31/node-v0.10.31.tar.gz).
When running the stratifiedJS buildscript:
$ git clone https://github.com/onilabs/stratifiedjs.git
$ cd stratifiedjs
$ ./sjs src/build/buildscript.sjs
Just now I had to run that last command 40+ times before it actually
succeeded (the failures were all SEGV crashes).
I'm afraid I haven't been able to narrow down the problem further - I'm
assuming it's memory corruption somewhere, so it's very difficult to know
where to start.
In node 0.10.26 (the previous version I was using), I would occasionally
get SEGVs, but only one every couple of days.
After running `ulimit -c unlimited` in my shell and triggering some more
crashes, I have tried to get a backtrace (using the `bt` command of `gdb
path/to/node core.PID`) but it doesn't look very healthy.
This backtrace appeared in 9 of the 10 dumps I tried:
#0 0x000000000279f701 in ?? ()
#1 0x00000000007fe746 in
v8::internal::HeapObject::HeapObjectShortPrint(v8::internal::StringStream*)
()
Backtrace stopped: previous frame inner to this frame (corrupt stack?)
----
The one outlier had this different backtrace:
#0 0x00001e3748604101 in ?? ()
#1 0x00007fff2e614ef0 in ?? ()
#2 0x00007fff2e614f28 in ?? ()
#3 0x0000000001b8c9f0 in ?? ()
#4 0x0000000000000005 in ?? ()
#5 0x00007fff2e614ee0 in ?? ()
#6 0x000000000080c61d in
v8::internal::JSObject::GetLocalPropertyNames(v8::internal::FixedArray*,
int) ()
Backtrace stopped: previous frame inner to this frame (corrupt stack?)
I don't know if I'm missing some debuginfo files to resolve those "??"
backtrace lines. GDB didn't instruct me to install any additional debuginfo
packages as it sometimes does.
