Qsys Error: Failed to elaborate classic module C:/Users/.../yysystem.ptf

[Altera_Forum]

Hello, 

i didn't touch my project for a while. Now i get the error: Error: Failed to elaborate classic module C:/Users/.../AppData/Local/Temp/alt7407_3755802541581721576.dir/0007_sopclgen/yysystem.ptf (254)  In other topics they told to close qsys, quartus and reboot the system but that all didn't help.  I only changed some c and h files on my NIOSII code (nothing related to the qsys) Is maybe the quartus installation corrupt? If maybe yes, how to reinstall it preferably (install over the old, remove reinstall)?  Quartus II 64Bit 12.1 SP1 installed  Below the last messages of th Generate log before the error occurs:   Info: Starting classic module elaboration. 1 sh (6408) C:\altera\12.1sp1\quartus\bin\cygwin\bin\sh.exe: *** fatal error - cygheap base mismatch detected - 0xE708D0/0x612708D0.

So i made a diff of the two versions, see pictures:  https://alteraforum.com/forum/attachment.php?attachmentid=14549&stc=1   https://alteraforum.com/forum/attachment.php?attachmentid=14550&stc=1   But there are only .c, .h files and .cproject and Makefile which are different, and all in the "..\software\ALD02070_socket" and not in the "..\software\ALD02070_socket_bsp" folder! In my opignion, to generate the QSYS i don't need any files in the software folder or are i'm wrong? First i need to generate the QSYS, then generate the bsp, and then compile the software. So i think that the QSYS is not dependent of all in the software\...socket folder...  Sorry, the picture SVN_Folders.gif is automatically reduced to a very low quality even it is only 50kB... So i try to load it in two separate pics..
