Thanks for your reply,



I did what you said and get the following error message:



ASSERT FAIL: dlmalloc.cxx [ 771] void Cyg_Mempool_dlmalloc_Implementation::do_check_chunk() (cyg_uint8 *)p + sz <= (cyg_uint8 *)(((mbinptr)((char*)&(av_[2*(0) + 2]) - 2*(sizeof(Cyg_Mempool_dlmalloc_Implementation::Cyg_dlmalloc_size_t))))->fd)



What do you suggest me doing?



Regards

Alperen
