Thanks @tejohnson for looking into this !
I encounter this bug when I link a very large ELF file, and get an optimization remarks file(YAML format ) about 700MB and containing about 9000000 lines.
I try to write a small testcase to for this.
It seems that we create the optimization remarks file in `lto::setupLLVMOptimizationRemarks()` and get a `ToolOutputFile`, I did not find an option which controls the underlying buffer size used by `ToolOutputFile`.
Could you give me some hint or suggestions? Thanks!
