Someone must examine and confirm this is a valid issue and not a duplicate of an existing one.
Milestone
As per
google/oss-fuzz#5442
Some Go fuzzer programs (configured with whatever oss-fuzz does to combine Go with the address sanitizer) are crashing with:
The actual Go code under test does not spawn its own goroutines, although it does involve asm code which IIUC is similar to cgo:
https://github.com/google/oss-fuzz/blob/master/projects/go-snappy/fuzz.go
https://github.com/golang/snappy/blob/master/decode.go
https://github.com/golang/snappy/blob/master/decode_amd64.s
Another comment in that 5442 issue says:
So perhaps the asm thing is unrelated??
Any suggestions on what to try next?
