Arch Linux User Repository

Greetings,

@Falkenber9, thank you very much for this. Yes, I recall this hitting the mailing list. I forgot to test whether it affected the GDB build. Thanks for reminding me. Also, thanks for reminding me I had to update the PKGBUILD to GDB 8.1.1; it was released 13 days ago [at the time of writing]. Luckily for us, the issue was fixed for the 8.1.1 release so the patch is no longer needed [1]. I have updated the PKGBUILD accordingly.

Still, thanks for the reminder and for the patch.

Cheers,

Orlando.

Maybe it is helpful for someone else:

As a consequence of this bug I had to patch the source by the following patch: https://sourceware.org/ml/gdb-patches/2018-05/msg00863.html
