Was that stock Cygwin gdb that crashed? Try this:
$ cat stest.c #include <sys/types.h> #include <sys/stat.h> int same_tty_p (int fd1, int fd2) { struct stat stat1, stat2; return (fstat(fd1, &stat1) >= 0 && fstat(fd2, &stat2) >= 0 && stat1.st_dev == stat2.st_dev && stat2.st_ino == stat2.st_ino); } int main(void) { printf("0/1: %d\n1/2: %d\n2/0: %d\n",same_tty_p(0,1), same_tty_p(1,2),same_tty_p(2,0)); printf("stat %d bytes\n", sizeof(struct stat)); } [EMAIL PROTECTED] ~ $ gcc -o stest stest.c [EMAIL PROTECTED] ~ $ ./stest 0/1: 1 1/2: 1 2/0: 1 stat 96 bytes $ nm stest.exe | grep fstat 00402970 T __fstat64 004060a4 I __imp___fstat64 004060e0 I __imp__fstat 004027a0 T _fstat Make sure struct stat is 96 bytes and you are calling fstat64. -- Brian Ford Senior Realtime Software Engineer VITAL - Visual Simulation Systems FlightSafety International Phone: 314-551-8460 Fax: 314-551-8444 -- 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/
