C++ string assign SIGSEGV

Hi,

I am using a string object in an element written in C++ code.

This is gstreamer 0.10.21
libstdc++ (gcc 4.2.3)

This line SIGSEGVs:

hhivvrenderersink->p.sWindowName = "Virtual view renderer";

Backtrace:

(gdb) bt
#0 0x00007fdc340f7ee0 in std::string::assign () from /usr/lib/libstdc++.so.6
#1 0x00007fdc35576849 in init_params (hhivvrenderersink=0xb46120) at /usr/include/c++/4.3/bits/basic_string.h:931

#9 0x000000000040651b in main (argc=2, argv=0x7fff4016c3d8) at gst-inspect.c:1374

Any suggestions why this could be happening?
Workarounds?

Best,

Mattias

Re: C++ string assign SIGSEGV

Check with valgrind.
probably hhivvrenderersink is a invalid memory.

1. Master the Basics
Foundational Skills: Ensure you have a solid understanding of both front-end and back-end technologies.
Front-End: HTML, CSS, JavaScript, React, Angular, or Vue.js.
Back-End: Node.js, Django, Ruby on Rails, or Spring Boot.
Version Control: Learn Git and platforms like GitHub or GitLab.
Databases: Gain proficiency in SQL and NoSQL databases like MySQL, PostgreSQL, or MongoDB.
DevOps Basics: Familiarize yourself with CI/CD pipelines, Docker, and cloud platforms.
2. Specialize Strategically
While being a generalist is valuable, specializing in areas like cloud development, AI integration, or cybersecurity can make you more marketable.
Focus on microservices architecture, as it's a key trend in modern full-stack development. Full Stack Classes in Pune
