I have a weird error and I can't find where it comes from. The only thing that appears in the logcat is :
01-10 17:07:10.665: A/libc(20449): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1)

I am trying to migrate the Kafka library being used in my application from kafka-node to node-rdkafka. My application is running on EC2 with Ubuntu 14 version and the node version is 12.14.0. I have tried two version's of node-rdkafka (2.10.0 & 2.10.1). Both the versions are throwing segmentation fault while deployment.
This is the error I am getting in gdb
Thread 16 "rdk:broker-1" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fffce7fc700 (LWP 32445)]
0x00007fffdd81ba9b in ?? () from /lib/x86_64-linux-gnu/libssl.so.1.0.0
What could be the possible cause for this issue?
I'm trying to run a script under IDLE in a fresh install of Python 3.7.0 on a Mac running OS 10.12.6, but it appears to crash once it hits "root = Tk()".

I have interrogated the tcl/tk library using:
print(root.tk.exprstring('$tcl_library'))
print(root.tk.exprstring('$tk_library'))
This reports the following:
/Library/Frameworks/Python.framework/Versions/3.7/lib/tcl8.6
/Library/Frameworks/Python.framework/Versions/3.7/lib/tk8.6
This appears to be correct given the information on Python.org here.
What should I be doing differently?
This app is build in Xamarin Studio 6.3 (Build 864) crashes at one instance. However, it does not crash every time but after some 4-5 scenarios it gets the crashed. And moreover, we are finding the crash report only with iOS 11. In iOS 10 it is working fine.

After adding the libraries to the project and instantiating everything according to the getting started guide (http://developer.skobbler.com/getting-started/android#) and the demo (http://developer.skobbler.com/support#download) I am running into some strange problems.
After adding the SKMapViewHolder to an activity, the app crashes and logcat returns the following:
06-05 14:22:48.388 1976-2013/com.x.app E/Adreno-ES11﹕ <qglDrvAPI_glDeleteTextures:371>: GL_INVALID_VALUE
06-05 14:22:48.388 1976-2013/com.x.app A/libc﹕ Fatal signal 11 (SIGSEGV) at 0x00000004 (code=1), thread 2013 (Thread-885)
This is happening on a USB Nexus 5 and N5 emulator. On running it with an N7 (2012) emulator it's just returning the second libc error.
Without Petsc, I can see which files, which functions, and which lines an error occurs and is propagated from. With Petsc, I always receive the same error message.
Is there any flag in Petsc that I'm missing?
Thanks.

Your code has generated a SEGV, probably by illegally accessing memory. As the error message recommends, you should run using valgrind or gdb, which will allow you to see the stack.
