System Information
Operating system: Windows
Graphics card: N/A

Blender Version
Broken: b90fec5d46
Worked: N/A

Short description of error
geonodes crashes with a stack overflow if you feed it a comically large graph

Exact steps for others to reproduce the error

Load the attached .blend

geotest_mandel.blend

Attach the mandel20 group to the output
Instant stack overflow

mandel7+8 do work but the perf is "not great"

i admit, this be an "uncommon" use of geo nodes, but still it shouldn't crash

stacktrace: P2116

the .blend above will only crash in debug, release mode miraculously survives, but here's a 40 iteration one that will also take down a release build
