Re: [Boost-users] boost::serialization throwing bad_alloc

Yes the stack trace seems incredibly deep for calling one line of boost
code (over 200 depth). I was hoping someone might guess what is going
wrong from the structure of the stack trace. I have looked through every
frame but can't see anything unusual, but the very fact it is so deep
feels wrong. The top-level object being serialized has some structure
but is not particularly complicated.

Yes it has worked in the past and works for small data sets now. However
I did not write the original code and suspect there may be some subtlety
which is leading the serializations to blow up in size and I can't find
it. Even seemingly small examples give rise to serializations of several
megabytes. The stack is of the order of 1Gb and cannot be easily
increased but I suspect the stack/heap size just lets it get into such a
deep mess before finally dying and the real problem is some conceptual
mistake in how my class's serialization has been implemented.

I seems strange, right. But have you been successful earlier? That is,
is there a point where it started failing? I guess you had smaller
programs before which worked.

Does it work with less data?

Does it work with increased stack size? Sure, a stack overflow should
not result in a bad alloc, but just try if nothing else helps. Your
stacktrace seems pretty large.
