[derekparker]

Did this happen after a particular command? Could you provide some more context around this?

[goen]

well the version of delve is e7c8bdc.
this happen immediatly after running a normal program by -run (built by go compiler 1.3.3)
sadly i don't have that program now here

[derekparker]

Was this just a normal Go program, or did it include cgo stuff? There is some Dwarf parsing that happens during Delve startup, which is where the SLEB parsing would be happening.

[derekparker]

No updated information on this, going to close it out.
