I'm issuing Cscope command using cmd in Winform.Sometimes it return successfully and some times gives(Most of the times) cygwin_exception::open_stackdumpfile: Dumping stack trace to cscope.exe.stackdump

I'm not able to identify the issue. Code of C# which turns into command is below:

Code :

CalledFunctionsNameCmdArgument = "/C cscope -k -u "+ FileNameAlongWIthDirectoryPath(in Windows Style i.e. G:\ABC\DEF.c) + " -L -3 " + @""".*""" + " | gawk '{$1=" + "\"" + "\"" + "; $3=" + "\"" + "\"" + ";sub(" + "\"" + " \"" + ", " + "\"" + "\"" + ");" + "sub(" + "\"" + " \"" + ", " + "\"" + "#" + "\"" + ");" + "print}' > " + OutputDirectory(In linux Style i.e. G:/ABC/DEF)

Output of Code Line mentioned above is:

/C cscope -k -u FileNameAlongWIthDirectoryPath -L -3 ".*" | gawk '{$1=""; $3="";sub(" ", "");sub(" ", "#");print}' > OutputDirectory

What can be the issue?

  • Without looking at cscope.exe.stackdump content is hard to say. Does the same problem happen in cygwin for the same data ? – matzeri Jul 03 '16 at 06:03
  • No when I run the same command in even in CMD ,I do not get any such error. – Naeem Khan Jul 03 '16 at 08:18
  • I have added the content to the question. – Naeem Khan Jul 03 '16 at 08:28
  • There is one more thing that i noticed.Visual studio is installed in C:\ directory and i run my code form there. But when i was issuing command on CMD,I was in the directory where my files resides i.e. G:\.NOw i issued the command when i was in C:\ on CMD and the same exception occurred. Now I think issue is of accessing the file.But how should i solve this problem? – Naeem Khan Jul 03 '16 at 08:43
  • No.If i issue the command in Cygwin terminal,I do not get such issues. – Naeem Khan Jul 03 '16 at 11:06
  • Though I solved it by placing files in the bin directory of winform project.But i still get errors when files are outside of Project Folder. – Naeem Khan Jul 03 '16 at 15:12
  • If cscope is a cygwin one, use POSIX style for input and ouput with proper escape. PS: cscope is available in as cygwin package. – matzeri Jul 04 '16 at 05:07
  • I guess problem is not of POSIX style.I run the same command for different files in the same directory one by one and it gives error for only few.Problem is related to Permission of files but i am not able to solve it. – Naeem Khan Jul 04 '16 at 09:13

Though I could not find the exact cause of the problem but i guess it was of File permission.I needed to edit the file (Result of another command "unifdef") and saved the result in another file,then providing those resultant files to the cscope did not create problem.Saving file after applying unifdef command , somehow changed the file permissions(I guess not because of unifdef but saving the file through Command Prompt changed the Permissions of files ).
