Bug#1019056: clang-14 fails to run with "Illegal Instruction"

[Vladimir Smirnov]

Package: clang-14
Version: 1:14.0.6-2
Severity: important
X-Debbugs-Cc: civil.over at gmail.com

Dear Maintainer,

When I'm trying to run clang-14 (actually happens for all clang
versions) it wails with Illegal Instruction. Full stacktrace:

# clang-14
PLEASE submit a bug report to
https://github.com/llvm/llvm-project/issues/ and include the crash
backtrace, preprocessed source, and associated run script.
Stack dump:
0. Program arguments: clang-14
1. Compilation construction
#0 0x0000003fc9ac0b0c llvm::sys::PrintStackTrace(llvm::raw_ostream&,
int) (/usr/lib/riscv64-linux-gnu/libLLVM-14.so.1+0xe7db0c)
Illegal instruction


I expect it to actually run and work fine. Also I'm sure it used to work
some time ago, but I haven't used that board for a few months and after
package upgrade it starts to fail consistently.
