Even if I solve the call to the right compiler we would still need to solve 
the dependency. Pino: maybe harcoding the clan version like we do in qtt 
creator?

Bug#915390: clazy: Segmentation fault compiling any file

[Lisandro Damián Nicanor Pérez Meyer]

For what I could see in the source the solution is to either set CLANGXX 
(maybe check if it is not defined and then define it?) or modifying the script 
in another way.

At least in unstable this is not a problem right now as the default LLVM is 
now 7, but a more robust solution could help.

I had clang (and thus clang-6.0) installed.  I tried again by installing
clang-7, but with similar results.

In fact, the clazy script makes this call, as shown in the original report:

/usr/lib/llvm-6.0/bin/clang -cc1 -triple x86_64-pc-linux-gnu -emit-obj ...

so it seems it is using clang-6.  However,

> ldd /usr/lib/x86_64-linux-gnu/ClangLazy.so
linux-vdso.so.1 (0x7fff6b6da000)
libLLVM-7.so.1 => /usr/lib/x86_64-linux-gnu/libLLVM-7.so.1 ...

so the plugin is built against LLVM 7.

Chaging the script to call clang-7 instead results in no errors, so it
should be a matter of adjusting it and requiring clang-7 in d/control as
a dependency.

Regards,

Alberto

Clazy calls clang, so maybe that's what's missing. I can't tell you right
now which package it is, but should be easy to find.

Package: clazy
Version: 1.4-3
Severity: grave
Justification: renders package unusable

Dear Maintainer,

attempting to compile any file on my system results in a segfault.
Could it be that a runtime dependency is missing from d/control?
