Package: libunwind8
Version: 1.2.1-10~deb10u1
Severity: normal
Dear Maintainer,
While trying to use heaptrack to debug a memory leak in lxpanel I found that
libunwind8 which heaptrack is using seems to segfault on armhf.
In case it helps I've rebuilt libunwind8 manually with --enable-debug to get
extra debug output below.
$ UNW_DEBUG_LEVEL=1 heaptrack --debug /usr/bin/lxpanel --profile ranma-test
heaptrack output will be written to "/home/pi/heaptrack.lxpanel.11000.gz"
starting application in GDB, this might take some time...

done.
