            Bug ID: 31726
           Summary: When compiling a file with >= 202 gtest test cases,
                    clang-cl dies with  Assertion `(NumGaps == 0 || Bias <
                    MaxDefRange) && "large ranges should not have gaps"'
                    failed.
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: DebugInfo
          Assignee: unassignedbugs at nondot.org

Repro coming; it's not very small though. (But fairly regular.) Reduced from
https://bugs.chromium.org/p/chromium/issues/detail?id=680947

If the CodeLocation() ctor is changed to take const char* instead of
std::string, then the crash goes away, and the file builds like twice as fast.
