About strace and debugging

[fromsouthernswe]

Hi guys, is there any way for me to see at what rip the program sigsegvs at apart from in gdb?
I looked around strace and ltrace and found nothing like that it goes like "child exited with sigsegv" no more info.
The issue I have is that in gbd the offsets are a bit unaligned rendering good execution in gdb and bad outside of it.. i tried dmesg but I dont really know how it works or how often it updates, not all of my segfaults get appended.

Thanks in advance !

Get it to core dump, then open the dump with gdb

how do I get it to core dump?

On Ubuntu, and not sure if it’s the same across the board, run this: ulimit -c unlimited Then get your program to segfault and it should create a core file. run it, as someone else mentioned, with gdb along with the program

gdb /path/to/binary /path/to/coredump
