Hello,
this bug is reported to debian, because it looks like a packaging issue
rather than a bug in iwyu itself.
When trying to compile a file containing the following headers iwyu
fails to compile the file:
- <random> introduced in C++11
- <algorithm> only in C++11 mode because it includes <random> there
- <limits.h>
GCC and clang are working fine on this system.
