Bug ID: 480739
Summary: heaptrack_gui crashes on analysing recorded trace
Classification: Applications
Product: Heaptrack
Version: 1.5.0
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: m...@milianw.de
Reporter: arvid.norlan...@epiroc.com
Target Milestone: ---

heaptrack_gdb_session.txt
SUMMARY
This happens both on 1.3.0 (packaged by ubuntu 22.04) as well as latest git
master (claims to be 1.5.80, commit 1a849114c6c2269725fd137ff4114d7a1b6aef9e).
The below gdb session is from latest git.
STEPS TO REPRODUCE
1. Run heaptrack on proprietary program (sorry, I don't seem to be able to
reproduce it on a trivial program): "heaptrack -r -o "%p.heaptrack" program
--flags"
3. After 60 seconds, stop program from running (the program doesn't have a
built in exit feature, it is normally cross compiled and run as the only
program on an embedded linux system).
4. Run heaptrack_gui on resulting file
5. heaptrack_gui prints a bunch of errors and warnings, then crashes
OBSERVED RESULT
I have attached the full GDB session as a file as as it was rather long. Here
is some of the most pertinent info for searchability though:

The X11 connection broke (error 1). Did the X11 server die?

EXPECTED RESULT
It shouldn't crash? If the file is corrupt it should probably error out rather
than crash.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Ubuntu 22.04
KDE Plasma Version: KDE Plasma 5.27.10
KDE Frameworks Version: 5.104.0
Qt Version: 5.15.3
Running on X11.
ADDITIONAL INFORMATION
So, I tried to provide you with the information anonymised file, but:
$ tools/anonymize 2161909.heaptrack.raw.zst bug_report_data.gz
gzip: 2161909.heaptrack.raw.zst: not in gzip format
# Well that doesn't seem to work...
$ zstdcat 2161909.heaptrack.raw.zst > tmp
09.heaptrack.raw.zst : Read error (39) : premature end
# Hm... Possibly related?
Then I ran the anonymisation tool on that converted tmp file, but unfortunately
it still leave paths and files names in it. So I cannot upload it as is. If you
know of a way to anonymise this properly, or if there is anything I can do to
help debug this, please let me know!
