Hi,

May I know, if this bug is going to be fixed in binutils and in which version? 

Any heads up will be appreciated.

Thanks for reply Cheng. But could you please help me to know, the version of
binutils and version of gcc having the fix of this issue?

Knowing fixed-in version (of binutils and gcc) will be very helpful.

Looking forward for reply.

Many Thanks,
Trupti

Not really.  I can confirm that the test cases do not fail when tested with
binutils 2.35 (with sanitization enabled) and with any binutils all the way
back to 2.30 if sanitization is not enabled.

Given that the bug was reported in 2018-12 and assuming that it was fixed at
some point in the 6 months after that, then the nearest binutils release that
would have included the fix is 2.33.

I hope that this helps.

Cheers
  Nick
