Bug ID: 39520
Summary: File mapping handles are leaked
Product: compiler-rt
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: profile
Assignee: [email protected]

This means that gcda files, when gcda files from a previous execution exist,
are kept open until the process terminates.
This makes it impossible to profile subset of a program execution (where you
want to flush gcda files and remove them before the beginning of the region of
interest, then flush them at the end of the region of interest).
https://reviews.llvm.org/D51974 should fix this.
