<pre>The `scan-build` perl script installed into `/usr/bin/scan-build` contains an
extra unicode-char <U+200B> which trips up the perl interpreter.
To reproduce:
"deb <a href="http://apt.llvm.org/xenial/">http://apt.llvm.org/xenial/</a> llvm-toolchain-xenial-7 main" >
/etc/apt/sources.list.d/llvm-latest.list
apt-get update
apt-get install clang-tools-7
/usr/bin/scan-build-7
Output:
Unrecognized character \xE2; marked by <-- HERE after /]*$)/ or
<-- HERE near column 116 at /usr/bin/scan-build-7 line 1082.
Inspecting the file /usr/bin/scan-build-7 at line 1081-1083 (with e.g. vim or
less)
$Cmd =~ /(.*\/?llvm-gcc[^\/]*$)/ or
<U+200B> $Cmd =~ /(.*\/?clang[^\/]*$)/ or
$Cmd =~ /(.*\/?ccc-analyzer[^\/]*$)/) {
shows the extra <U+200B> 'ZERO WIDTH SPACE' character.
If I remove this character everything works as expected.
It doesn't seem to exist inside the sources themselves, at least the ones
offered for download (<a href="https://releases.llvm.org/download.html#7.0.0">https://releases.llvm.org/download.html#7.0.0</a>), so I
guess it is a packaging-only problem.
The package downloaded is: (snips from apt-get install)
