Memory leak reported by valgrind
Last modified: 2013-11-20 09:48:20 EST
When running remote-viewer through valgrind, I got this trace:
==13623== 48 bytes in 2 blocks are definitely lost in loss record 7,424 of 13,299

This is with libusbx-1.0.17-1.fc20.x86_64 (happened with 1.0.16 as well).
I couldn't spot an obvious leak looking at the code. I can reliably reproduce it, so let me know if more tests are needed. I'm logging this here to not forget, let me know if this should go elsewhere.
I believe this may be fixed by the 3 commits I've just pushed to libusbx git:
Can you build libusbx from master and give that a try?
Thanks & Regards,
Hmm just tried to reproduce, but I did not manage to reproduce, even with f20 libusbx, and I did not leave enough details about the exact setup I was using :(
Let's just say it's fixed, and I'll reopen if I see that again.
