clang errors

While trying to upgrade databases/arangodb33 to the latest upstream version, I encountered these clang crashes. Attached are preprocessed files and associated invocation scripts.

To confirm, this is Clang 5.0 in 11.1?

(In reply to Ed Maste from comment #1)

Hi Ed, no, this is 4.0 from 11.1-RELEASE-p8. I've just opened a similar ticket, the report is from the same system.

Vlad, the tarball contains multiple cpp files and shell scripts:

DaemonFeature-3601e9.cpp
DaemonFeature-3601e9.sh
c-b2d77e.cpp
c-b2d77e.sh
gtest-all-cecbdb.cpp
gtest-all-cecbdb.sh
lru_cache-f2927e.cpp
lru_cache-f2927e.sh
v8-buffer-348b23.cpp
v8-buffer-348b23.sh
v8-conv-eb2c30.cpp
v8-conv-eb2c30.sh

which one caused the particular crash "Access past stack top"?
