Segmentation fault running SampleApp

[marcardenas]

IMPORTANT: Before you create an issue, please take a look at our Issue Reporting Guide.

Briefly summarize your issue:

Running SampleApp results in a segmentation fault after getting into Connecting state. This is the tail of the log: the segfault always occurs after the ThreadPool notification

What is the expected behavior?

SampleApp should indicate that is on IDLE state (client side) and the GUI should change to "Press and hold 'A' to speak" (server side), allowing me to perform a request.

What behavior are you observing?

GUI does not change state and SampleApp closes prematurely.

Provide the steps to reproduce the issue, if applicable:

1. Open index.html file with a supported browser. In this case, it was used minimal, a qtwebengine based web broser (https://doc.qt.io/qt-5/qtwebengine-webengine-minimal-example.html). This command should open the GUI in the screen
   ./minimal ~/sdk_folder/ss-build/modules/GUI/index.html --no-sandbox
2. Run SampleApp
   .~/sdk_folder/ss-build/modules/Alexa/SampleApp/src/SampleApp -C /path/to/AlexaClientSDKConfig.json -C /path/to/SmartScreenSDKConfig.json -L DEBUG9

Tell us about your environment:

I've built the application using STM32MP1 Developer Package, a toolchain to cross-compile applications for the MP1 (https://wiki.st.com/stm32mpu/wiki/STM32MP1_Developer_Package#Installing_the_SDK). All the libraries and binaries were deployed then to the MP1 using SCP.

NOTE: I've built avs-device-sdk and tested SampleApp successfully before on the same board

What version of the AVS Device SDK are you using?

AVS SDK v1.19.0
SmartScreen SDK v2.0.2

Tell us what hardware you're using:

• Desktop / Laptop
• Raspberry Pi
• Other - tell us more: ST's STM32MP157 DK2 board (ARM A7 32 bits processor + M4 MPU)

Tell us about your OS (Type & version):

• Linux
• MacOS
• Raspbian Stretch
• Raspbian Jessy
• Other - tell us more: Custom Linux distro based on OpenSTLinux. This distro was built using Yocto + OpenEmbedded (Thud branch layers)

Hi @marcardenas ,

Thanks for reaching out, could you try reversing the startup order of the browser and SampleApp so that the SampleApp is started before the browser connection is established.

If you still experience crashes after doing this please could you provide a stacktrace to help us investigate further.

Thanks
