the condition variable may be signaled even if the initialization by the other thread is not done yet. Handle spurious wakeups the same way as timeouts: go around once more from the beginning. Fixes dotnet#96872
if we goto retry_top, don't set up a new handle frame that lacks a matching HANDLE_FUNCTION_RETURN_VAL. Instead setup the handle frame once upfront

@lambdageek , Is this change (#96903) available on a daily build. I am seeing the same issue ("Assertion at /__w/1/s/src/mono/mono/metadata/object.c:657, condition `lock->done' not met") after updating to dotnet 8.0.100. Tried the "8.0.200-preview.24064.2" and that didn't have the fix either(crashes) . |

* mono_runtime_class_init_full: handle spurious wakeups the condition variable may be signaled even if the initialization by the other thread is not done yet. Handle spurious wakeups the same way as timeouts: go around once more from the beginning. Fixes dotnet#96872 and dotnet#96804 * fix unbalanced handle frames if we goto retry_top, don't set up a new handle frame that lacks a matching HANDLE_FUNCTION_RETURN_VAL. Instead setup the handle frame once upfront
