Is this a Linux library? I have seen this kind of stack usage a few time when code written for Linux is ported to NuttX. Linux code sometimes allocates huge arrays on the stack. This is harmless on Linux since the stack is virtualized and only backed by RAM if actually used. But it can cause catastrophic memory usage in an embedded system with a flat address space.
