Source: aptitude
Version: 0.8.2-1
Severity: normal
Hi, since some months, the default pbuilder installation (the default uses
aptitude resolver) crashes
when under a qemu environment.
steps to reproduce
pbuilder-dist sid arm64 create
pbuilder-dist sid arm64 update
crash.
I tried to gdb but I didn't have to much luck in having a backtrace
gdb aptitude

you can find some bits in the discussion below
https://lists.debian.org/debian-mentors/2016/07/msg00644.html
probably this is a bug in qemu itself, but I thought it was better to report it
here,
to make you aware of the issue.
Switching to apt resolver or another one "fixes" the issue.
as usual, feel free to reassign or give me some pointers to debug further the
issue
thanks a lot,
Gianfranco

This has been fixed in qemu 5.0 (maybe earlier, but 5.0 definitely works).
The buster version (3.1) does not work still.
Thanks,
