This has absolutely nothing to do with SVN GCC. tcsh 6.15.0 is
BROKEN.
In one xterm:
mobile:kargl[204] cd tmp
mobile:kargl[205] cat > h.c
#include <stdio.h>
int main(void) {
printf("hello\n");
return 0;
}
mobile:kargl[206] cc -o z -g h.c
mobile:kargl[207] gdb z

The 'killall gdb' is the cause of the 'Terminated' message in the
first xterm.
