[PATCH] D143369: [llvm-profdata] Fix bug llvm-profdata crashes when reading a text sample profile with an empty line with spaces.

[Rainer Orth via Phabricator via llvm-commits]

ro added a comment.

I've taken the smallest failing testcase (`LLVM :: tools/llvm-profdata/sample-remap.test`) and reduced it further to

  $ cat in
  main:184019:0
   4: 534
   4.2: 534
  $ llvm-profdata merge -sample -text in -o out

Without your patch, the output is identical to the input, with it, I get

  main:184019:0
   4: 1068

instead.  I'm completely unfamiliar with both the input format and the code, so I've not yet tried looking deeper.
