----------------------------+-----------------------------------------------
 When running my program with limited heap size (-H128m) and/or using the
 compacting procedure (-c) in garbage collection, the program crashes with
 the following message:

 Segmentation fault/access violation in generated code

 It seems that the segfault occurs the first time the garbage collector
 runs as the log file generated with -S contains the headline only.

 The program runs fine without the -M and -c options.

 This problem is critical from my point of view as I cannot control what
 kind of data the customer will supply to the algorithm and I would the
 prefer the algorithm (then deployed as a DLL) to gracefully report a heap
 overflow instead of eating all the customer's terminal server's memory.

 Let me know how I can help to fix this bug.

 As the source code is proprietary, I cannot attach it here.
