I finally updated to the current tip (1.53.84) but now in one plugin I get an assertion in Time::getApproximateMillisecondCounter() (juce_Time.cpp / Line 279):
jassert (TimeHelpers::lastMSCounterValue != 0);
This happens when loading an Image with ImageCache::getFromMemory().
When I put
before the image loading the assertion doesn’t trigger, so I assume this is some initialisation issue in Time.
