The program crashes after 5-10 minutes since startup (provided the periodic check always sends files) at curl_easy_perform() with the following stack trace:
As Tomalak mentioned, we can't do a lot if we cannot reproduce this problem. A lot of users run libcurl and nobody else has reported this problem before.
Some debugging ideas:- If you build libcurl debug enabled (with -g) you might get more details in the stack trace from the crash, which might help.
- If you run with gdb and catch the crash, it might help to inspect local variables and the stack trace.
- Try building your application with memory/address sanitizers or run with valgrind to catch mistakes in your code that could be what makes libcurl trip.
libcurl/7.74.0-DEV
I trust you built this from a release tag and it isn't just a random commit from the middle of the release cycle? The "-DEV" part there reveals it isn't from a release package.
