Cygheap issue with Nios II tools

--- Quote Start ---

Hello everyone,

I'm facing an error from time to time when I execute nios2-xxx tools or when I start debugging in Nios II Eclipse.

-> I'm getting a cygwin error as follows:

      0  perl (5284) C:\altera\13.0sp1\quartus\bin\cygwin\bin\perl.exe: *** fatal error - cygheap base mismatch detected - 0x612708D0/0x8208D0.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.
/cygdrive/c/altera/13.0sp1/nios2eds/bin/sh_pl.sh: line 2:  5372 Segmentation fault      PERL5LIB=`cygpath -u "$SOPC_KIT_NIOS2/bin"` perl "${SH_PL:-$0.pl}" $@

I've already found some posts in the net about this issue related to Win7 64bit, but didn't try them yet since I don't want to ruin my Quartus installation.

Btw, I have no other cygwin installation on my system.

Is there any solution to avoid that error and also avoid rebooting the PC?

Best regards

Hi,

This error is still reproducible with QuartusII 14.0.
