What are the recommended ways to generate a backtrace for crash in protected binary?

Re: License Expiry Bypass via system Clock Rollback

Probably you didn't understand the question, I'm compiling and running on same machine. My question is, let's say we protected a shared library xyz.so file and now we want to link protected library xyz_vmp.so to build a binary like this: gcc main.c -lxyz_vmp.so where main.c uses functions from libxy...

Thank for the answers, they were really helpful and positive for our scenario. our goal is to protect our Binaries as well as libraries .so files. For binaries, All good.

Re: License Expiry Bypass via system Clock Rollback

thanks for the confirmation. We are very satisfied with how the SDK secures our binaries and handles licensing logic, and but before purchasing the license for VMprotect, we want to confirm and try to fully automate our workflow.
