Hello! I am using Debian's gcc 4.2.1, and I am running into some trouble while
compiling logapp, available at http://logapp.sourceforge.net
Here are the details:
gcc -v -save-temps -Wall -O2 -c -o configuration.o configuration.c

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
For Debian GNU/Linux specific bug reporting instructions,
see <URL:file:///usr/share/doc/gcc-4.2/README.Bugs>.
make: *** [configuration.o] Error 1
Observation: The bug disappears if I remove -O2 from the compiler flags.
Should you require the preprocessed file, please tell me and I shall put it
somewhere where you can pick it up.
Thanks!
