Version 2.3.2 works fine; version 2.3.3 instead just keeps saying "...retry after 30 seconds", as if the pool server was unavailable (which is not the case).
The launch command is exactly the same for both versions:
minerd.exe -o stratum+tcp://ltc-eu.give-me-coins.com:3333 -O Username:Password
What's wrong here?
I can reproduce this (even if not consistently) on Linux under Wine using both the 32-bit and the 64-bit Windows binary. The issue disappears, however, if I replace the libcurl DLL provided with cpuminer 2.3.3 (libcurl 7.35.0) with the older libcurl DLL from cpuminer 2.3.2. After further testing, I was able to reproduce the issue with libcurl 7.35.0 and 7.36.0, but not with 7.34.0 or 7.33.0.
The problem keeps randomly happening.
Once it connects I can mine without problems for hours, but sometimes it simply doesn't connect and just gives the "...retry after 30 seconds" message. As before, 2.3.2 Always works; only 2.3.3 exhibits this behaviour.
