Issue ID: 20650
Summary: Cryptic error message when GC called in finalizer
Product: D
Version: D2
Hardware: x86_64
OS: Linux
Status: NEW
Severity: enhancement
Priority: P1
Component: druntime
Assignee: [email protected]
Reporter: [email protected]
Consider the following code:
class Foo { ~this() { new int; } }
void main() { new Foo; }
What I expected:
core.exception.ReentrantFinalizerException: GC called while finalizing memory.
Are your destructors @nogc?
What I got:
core.exception.InvalidMemoryOperationError@src/core/exception.d(647): Invalid
memory operation
This is cryptic at best and actively misleading at worst, due to the confusion
potential with segfaults. The error message should be made clearer.
