Looks similar to, but not exactly like, the issue in https://github.com/openwrt/packages/pull/13467#issuecomment-697290330.

it's a GCC bug. Can't do much about it.

[jefferyto]

Perhaps there is something in tor we can patch or disable to work around the bug, like https://github.com/openwrt/packages/pull/13467#issuecomment-700968333?

[neheb]

right. mallinfo however is not related. it's something else. I wonder if that bench binary is even needed.
