runtime error with go 1.14.2

predmond commented 4 years ago

I'm trying to update my code to use go 1.14.2. When I run my tests for code using gohs I'm getting a runtime error:

Any idea what could cause this?

runtime: pointer 0xc000433860 to unallocated span span.base()=0xc00042c000 span.limit=0xc000434000 span.state=0

Very strange, I updated the third-party library and the problem is not reproduced, can you try again?

@predmond If there is no other feedback I will close this issue.
