System: NetBSD martins.aprisoft.de 7.99.62 NetBSD 7.99.62 (GENERIC) #116: Thu Feb 23 13:03:58 CET 2017 martin%martins.aprisoft.de@localhost:/ssd/src/sys/arch/amd64/compile/GENERIC amd64
Architecture: x86_64
Machine: amd64
>Description:

When building -current on -current amd64 I get lots of (apparently non-fatal)
errors from ctfconvert:

....tools/bin/nbctfconvert -g -L VERSION -g alias.o
ERROR: alias.c: failed to get mapping for tid 955 ((null)) <3bb>

there are 159 similar lines.

The message, as is, is completely useless and should be fixed. Even better
would be to avoid the root cause.

>How-To-Repeat:

Do something like:

  ./build.sh -u -O /ssd/obj -E -D / -T /ssd/tools -x -V TMPDIR=/var/shm/btmp -j 12 -V BUILDINFO=Build locally, cvs.netbsd.org source tree date: 2017-02-23 12:10 UTC -V MKDEBUG=yes -V MKDEBUGLIB=yes build


>Fix:
n/a
