pthread_create segmentation fault with pthread_create.c 552
I am getting a segmentation fault right after I am creating a thread. The thread that I am creating is globally defined list. gdb descriptioncode Stdout does not print the print statement right after pthread_create. Would appreciate any help

Welcome to Stack Overflow. Please read the About and How to Ask pages now, especially the latter. We'll need an MCVE (Minimal, Complete, and Verifiable example) included in the question; sending us to somewhere offsite in an image isn't OK — we can't copy the code and experiment with it, all else apart.

t1
is probablyNULL
[or points to random memory] on your firstpthread_create
call, as it is the only value you pass in that could cause a segfault, but it's difficult to know without the rest of your code.

Thank you all for the suggestions. Will be better in the future. @CraigEstey You were right. I forgot to malloc what t1 was equal to. Thank you for pointing this out!
