Re: Re: Constant IDE crashes

This is a pretty generic error that happens whenever some heap corruption occurs. It means that during garbage collection, some system exception was generated (probably a messed up pointer or something) which caused an attempt to allocate an exception object, which caused the garbage collector to get invoked (again). The collector knows that this means there was some sort of problem, and gives this (cryptic) message. 

The thing to look for is whether any foreign manipulations are referencing invalid pointers, or otherwise causing a heap foulup. It is as easy to do when using the FFI in Corman Lisp as it would be if you were programming in C (unfortunately).
