Public bug reported:
I wanted to see what would happen if I removed all i386 packages (I am
on amd64) so I ran
aptitude -s remove '~ri386 ~i'
I got a segfault. I compiled aptitude with debug info and got this
backtrace:
#0 0x00007ffff5a518ef in _int_malloc (av=av@entry=0x7ffff5d94c00 <main_arena>,
bytes=bytes@entry=48)
at malloc.c:3326
#1 0x00007ffff5a5450e in __GI___libc_malloc (bytes=48) at malloc.c:2895
#2 0x00007ffff6347188 in operator new(unsigned long) () from
/usr/lib/x86_64-linux-gnu/libstdc++.so.6
#3 0x00007ffff7b42177 in pkgDepCache::SetReInstall(pkgCache::PkgIterator
const&, bool) ()
from /usr/lib/x86_64-linux-gnu/libapt-pkg.so.4.16
#4 0x0000555555795974 in aptitudeDepCache::internal_mark_delete
(this=0x555555daff30, Pkg=..., Purge=false,
unused_delete=true) at ../../../../src/generic/apt/aptcache.cc:1248
There then follow hundreds more repetitions of internal_mark_delete. I
am not sure if this is very deep recursion, or stack corruption, or
what.
I assume this is probably specific to the set of packages I have
installed. What is the best way for me to send the information that you
need?
