<pre>This appears to be a regression sometime between LLVM 9 and the current head of
master. When using llvm-symbolizer in interactive mode (i.e. without specifying
any addresses on the command-line and without feeding a file via stdin), it
produces the crash report message (but no backtrace) when the user presses
Ctrl+C to terminate the process.
Further investigation suggests that this only happens when the user provides
the input file on the command-line, and not until they have entered at least
one address. Additionally, on occasion I didn't see the message in my
experiments with this.
Example:
PS C:\Work\TempWork> C:\llvm\build\Debug\bin\llvm-symbolizer.exe -e test.elf
0x1234 <-- entered via stdin
??
??:0:0
<enter Ctrl+C>
PLEASE submit a bug report to <a href="https://bugs.llvm.org/">https://bugs.llvm.org/</a> and include the crash
backtrace.
PS C:\Work\TempWork></pre>
