Anyway, add me to the list of people having this particular problem. Unforunately, I have no clue what to do about it either, but I just wanted it to be noted that more than two people are having this issue. I am running Win XP, and all of the problems you have specified are also present on my machine exactly as you wrote.

I'm having troubles getting dumper.exe to work. I always get a zero-length core file. I have the lastest stuff as of tonight, I have read the FAQ and the man page, and I have searched the mailing list archive. Any help would be greatly apprieciated.
I am using: Windows 2000 SP3 Cygwin 1.3.21
My CYGWIN environment variable is set thusly:
~/crash: echo $CYGWIN nontsec error_start=C:\cygwin\bin\dumper.exe
I don't have core file sizes limited:
~/crash: ulimit -a core file size (blocks, -c) unlimited data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited open files (-n) 256 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) 2047 cpu time (seconds, -t) unlimited max user processes (-u) 63 virtual memory (kbytes, -v) 2097152
I have the following test program:
~/crash: cat crash.c int main( int argc, char *argv[]) { char *c = 0; c[0] = 6; }
Which I compile like this:
~/crash: gcc -g crash.c
When I execute my test program I get the following output:
~/crash: ./a.exe 5 [main] a 1944 handle_exceptions: Error while dumping state (probably corrupted stack) Segmentation fault (core dumped)
I also get a seperate cmd.exe window with the following contents:
18653 [main] dumper 1716 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION
19168 [main] dumper 1716 open_stackdumpfile: Dumping stack trace to dumper.exe.stackdump
And I get the following files:
~/crash: ls -l total 23 21 -rwxr-xr-x 1 Administ None 20655 Mar 14 22:04 a.exe* 0 -rw-r--r-- 1 Administ None 0 Mar 14 22:04 a.exe.core 1 -rw-r--r-- 1 Administ None 69 Mar 2 11:34 crash.c 1 -rw-r--r-- 1 Administ None 298 Mar 14 22:04 dumper.exe.stackdump
For good measure I have attached the output of cygcheck -s -v -r.
As a final note, before upgrading to the latest stuff, I was getting no core file at all nor a cmd.exe window.
