Stack usage of Flat buffer library

[blueshift155]

Hi,

I have a general question on the stack usage of the library.

• How much stack memory is needed for the library?
• Are there any stack usage related changes in the v1.12 over the v1.11?

The rationale for this question is when I put the latest library in RTEMs OS, there was a stack overflow error. And it is probably due to limited stack space set in the OS. However, the old v1.11 works just fine. Also, the v1.12 works on the Yocto Linux OS platform.

Is there any way through some defination or compiler instruction to make this work?

Help needed seriously.

That is a very general question. Stack usage for what? The base API (accessing a FlatBuffer) should have close to no stack usage. The JSON/schema parser could have a lot of stack usage, but is an optional component.

Show some code/stack trace of where exactly it is blowing up the stack. Most debuggers would allow you to view the address of any stack allocated variables, allowing you to track down where the biggest usage is happening.
