[jira] Created: (HARMONY-4882) [vm][gc] vm throws an assertion when
array size is big
[vm][gc] vm throws an assertion when array size is big
------------------------------------------------------
Key: HARMONY-4882
URL: https://issues.apache.org/jira/browse/HARMONY-4882
Project: Harmony
Issue Type: Bug
Components: DRLVM
Reporter: Alexei Fedotov
The following line produce an assertion in VM code:
Class.h:
unsigned calculate_array_size(int length) const {
[...]
assert((size & NEXT_TO_HIGH_BIT_SET_MASK) == 0); <<< crash
return size;
}
The VM should not crash. It should behave according to spec: if it cannot allocate an array, it should throw OutOfMemoryError.

[jira] Commented: (HARMONY-4882) [drlvm][gc] vm throws an assertion

Alexei Fedotov commented on HARMONY-4882:
-----------------------------------------
The local problem is incorrect conditional which precedes the assertion. There might be more problems along this code branch which was never taken before.
