I am a newbie and have installed Cygwin on a Windows XP machine using the default settings. I have compiled a faulty program called a.exe using the command gcc -Wall -g null.c I would like a core dump to be produced when the program fails. I have tried 3 methods (advice from these threads) so far but they have not worked. Method 1 Running ./a.exe results in the following error: 6 [main] a 5132 _cygtls::handle_exceptions: Error while dumping state (probably corrupted stack) Segmentation fault (core dumped) But there is not core file in my directory Method 2 I have added the following to my cygwin.bat file: Set CYGWIN=error_start=c:\cygwin\bin\dumper.exe Running ./a.exe results in a window to pop-up and reads: Setting bfd architecture: No error After the window closes the following message displayed in the terminal window: *** starting debugger for pid 4024, tid 4436 But the debugger never starts and no core file is produced Method 3 I modified the environment variable to be: Set CYGWIN=error_start=c:\cygwin\home\MDGCUSTOMER\wrapper_dumper.cmd Where wrapper_dumper.cmd has the following: c:\cygwin\bin\dumper.exe -d -c %1 %2 Running ./a.exe results in the following error: *** starting debugger for pid 3908, tid 5220 [6] main a 3248 try_to_debug: Fialed to start debugger, Win32 error 2 *** continuing pid 3908 from debugger call <0> 1454996 [main] a 3248 _cygtls::handle_exceptions: Error while dumping state (probably corrupted stack) 1487118 [main] a 3248 try_to_debug: Failed to start debugger, Win32 error 2 Segmentation fault (core dumped) Again, there is no core file produced Thanks for your help in advance -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
