Bug ID: 390893
Summary: Crash while profiling my app
Product: Heaptrack
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: m...@milianw.de
Reporter: jeremy.coulon.j...@gmail.com
Target Milestone: ---
Hello!
I have a complex (proprietary) and long running application that I am trying to
profile with heaptrack. I am afraid I can't make a simpler open source example
to reproduce the crash.
I often have the following crash after a few minutes of profiling. It appears
from random places in my application. Thus I don't think the bug is on my side.
I am profiling my app from the start (no live attaching).
I am running Ubuntu 16.04 LTS.
I compiled almost everything from source.
I tried different combinations of:
- heaptrack v1.0 tag
- heaptrack 1.0 branch
- heaptrack master branch
- libunwind debian/1.1-4 tag
- libunwind v1.2.1 tag
- libunwind v1.2-stable branch
- libunwind v1.3-stable branch but here I have compilation errors
With libunwind v1.2.1 and heaptrack master all unit tests from libunwind and
heaptrack are OK.

Please tell me if I can give you more debug information about this crash.
Thank you for your help.
