Exception raised in SpiderMonkey45Binding: error during FreeMem operat

Using mORMot '1.18.2923', if compiled with Delphi XE or Berlin, SpiderMonkey45Binding gives various errors. Could you help to check ?

PS: If compiled with Delphi 7, SpiderMonkey45Binding runs fine.

The situation remains the same after Updating to mORMot '1.18.2988'...

Can you comment whether you can at least reproduce this issue ?

We reproduce a issue - this is because FastMM FullDebugMode

{$IFDEF DEBUG} {$define FullDebugMode} {$ENDIF}

is enabled in your FastMM4Options.inc
Without this option enabled everything is fine. At the moment we do not know the reason. Looks like a conflict between FastMM in FullDebug mode and a nspr memory manager (SpiderMonkey use a memory manager from Netscape Portable Run-time nspr4.dll)

Thank you very much for your efforts in researching ! Because FullDebugMode is rather important for FastMM for finding memory leaks, I hope this incompatibility between FastMM w/ FullDebugMode and SpiderMonkey could be removed in future.
