Assertion failed: ctx->poseLength < 20

Question

Assertion failed: ctx->poseLength < 20

bl4ckb0ne opened this issue 2 years ago · 4 comments

I'm hitting the assertion here in src/survive_optimizer.c after a few minutes of run (varying from 2 mins to 15 mins)

Here's the log from survive-cli --force-calibrate after removing the config file in ~/.config/libsurvive/config.json. Both controllers (Valve Knuckles) are lying flat on my desk, untouched, and the HMD (Valve index) on my head.

I'm seeing this error as well when using the https://github.com/asymingt/libsurvive_ros2 ros driver

I've been running the node in the background this morning. Not the same error, but here's a backtrace from one assert that was hit at runtime, admittedly in DebWithRelInfo mode.

FWIW running in release shuts down the assert and works fairly fine.

@bl4ckb0ne I should be able to relatively easily compile in Release mode, but I'm worried that these asserts signal some bigger issue that might be masked if we disable them.
