Compiling in a terminal causes "modified by external application"

When the option 'Preferences' -> 'Behavior' -> 'Save files when changed' is *not* selected, compiling an opened *c* source file in a terminal causes a notification `" was modified in an external application. Do you want to load it again or continue your editing?"` to be shown. Selecting `Continue` will cause the notification to be shown again until `Load` is chosen.

If the option 'Preferences' -> 'Behavior' -> 'Save files when changed' *is* selected, the editor jumps to the top of the file.

The compilation command is:
`../opt/mingw32ce/bin/arm-mingw32ce-gcc -x c -L -l -mno-thumb-interwork -o `
which shouldn't modify the source file (and doesn't according to the output from `ls -lortha`).
