Hi,
I have some nodejs-program which uses up all memory available. When calling
gc frequently, the problem can be avoided. But whithout gc
the problem occurs regardless of architecture and node version (tried
0.10.5 and successors/linux windows arm)
On linux, in order to avoid machine lock-up, using ulimit -v 2000000 (Thats
something like 2 GB), I get the msg
FATAL ERROR: Malloced operator new Allocation failed - process out of
memory (If I dont use ulimit, node will just use up all
available memory and swap-space, and you have to drink coffee until machine
settles down to usable state)
When debugging with gdb and setting bp in .../v8/src/allocation.cc:41, I
get a giantic stack-trace, which starts like that:

which continues up to a deepth of
#1469 0x0000000000000000 in ?? ()
with last non ??
#1326 0x0000000000b4b560 in v8::internal::Runtime_LazyRecompile (args=...,
isolate=0x130d070) at ../deps/v8/src/runtime.cc:7917
so this looks to me like some endless recursion in my (its actually a
library I'm using (sqlite emscripten js version)) program.
What I would like to do is to turn this error somehow in a
javascript-stacktrace to be able to figure out where that happens. So is
there some easy way to make
that thing throw an exception into my javascript-code? While testing I
could also change the code in allocation.cc but coz I'm not familiar with
node/v8 I would appreciate some help or advice....
Cheers, Peter
