cmd/compile: possible PGO miscompilation in biogo-igor benchmark #69614

Open mknyszek opened 4 hours ago

mknyszek commented 4 hours ago

The biogo-igor benchmark part of Sweet has been failing regularly at tip in the end-to-end test. It specifically fails when being run under PGO.

Broken out from #56958.

Example failure looks like:

error: piling: record on line 0; parse error on line 1, column 3: strconv.ParseInt: parsing "16243440": value out of range
