Possible installation problem of Clang 8 C++17

[nomennescio]

When running my C++ code, which has a bug in it, the runtime generates this error:

UndefinedBehaviorSanitizer:DEADLYSIGNAL
==1==ERROR: UndefinedBehaviorSanitizer: FPE on unknown address 0x0000004258f5 (pc 0x0000004258f5 bp 0x000000f695c0 sp 0x7fff51625aa0 T1)

UndefinedBehaviorSanitizer can not provide additional info.

Googling mentions that the

==1==WARNING: invalid path to external symbolizer!
==1==WARNING: Failed to use and restart external symbolizer!

point to an installation problem with Clang 8 C++17.

Could you check this?
