Bug Description

On Ubuntu 16.04 I ran a
valgrind --leak-check=yes -v
against a debug binary I had compiled using g++ (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609.

When I run without the -v option there is no crash reported. With the -v option I have generated a bug prompt 2 runs for 2 (the first time I had out of date packaged though).

#136538 was suggested as a possible, and it could be that but as it was a long time ago I made a new one. That itself says it could be #97531 but that claims to now no longer be an issue.

Interesting... I installed the valgrind-dbg package and I no longer get an error report when I attempt to recreate the problem.

Before adding debug this was the output:

==4182== Your program just tried to execute an instruction that Valgrind
==4182== did not recognise.  There are two possible reasons for this.
==4182== 1. Your program has a bug and erroneously jumped to a non-code
==4182==    location.  If you are running Memcheck and you just saw a
==4182==    warning about a bad jump, it's probably your program's fault.
==4182== 2. The instruction is legitimate but Valgrind doesn't handle it,
==4182==    i.e. it's Valgrind's fault.  If you think this is the case or
==4182==    you are not sure, please let us know and we'll try to fix it.
==4182== Either way, Valgrind will now raise a SIGILL signal which will
==4182== probably kill your program.

==4182== Your program just tried to execute an instruction that Valgrind
==4182== did not recognise.  There are two possible reasons for this.
==4182== 1. Your program has a bug and erroneously jumped to a non-code
==4182==    location.  If you are running Memcheck and you just saw a
==4182==    warning about a bad jump, it's probably your program's fault.
==4182== 2. The instruction is legitimate but Valgrind doesn't handle it,
==4182==    i.e. it's Valgrind's fault.  If you think this is the case or
==4182==    you are not sure, please let us know and we'll try to fix it.
==4182== Either way, Valgrind will now raise a SIGILL signal which will
==4182== probably kill your program.

==10035== Your program just tried to execute an instruction that Valgrind
==10035== did not recognise.  There are two possible reasons for this.
==10035== 1. Your program has a bug and erroneously jumped to a non-code
==10035==    location.  If you are running Memcheck and you just saw a
==10035==    warning about a bad jump, it's probably your program's fault.
==10035== 2. The instruction is legitimate but Valgrind doesn't handle it,
==10035==    i.e. it's Valgrind's fault.  If you think this is the case or
==10035==    you are not sure, please let us know and we'll try to fix it.
==10035== Either way, Valgrind will now raise a SIGILL signal which will
==10035== probably kill your program.

Output looks the same to me.  Could it be that Valgrind's attempt to generate something useful for a bug report, when it has not debug symbols, causes some undesirable behaviour?

Whether that is the case or not I shall try to follow: 
==10035== 2. The instruction is legitimate but Valgrind doesn't handle it,
==10035==    i.e. it's Valgrind's fault.  If you think this is the case or
==10035==    you are not sure, please let us know and we'll try to fix it.
==10035== Either way, Valgrind will now raise a SIGILL signal which will
==10035== probably kill your program.
And post any bug report references back here (unless I find it is already fixed in a new version)
