Thank you for this error report and I can reproduce this error situation. I
will hopefully fix this with the next release.
Best Regards

Betreff: Optimized Newscache crashes?
Hello,
On Fedora Core 1, with gcc-3.3.2-1.athlon.rpm (aka)
> gcc -v
Reading specs from /usr/lib/gcc-lib/athlon-redhat-linux/3.3.2/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--disable-checking --with-system-zlib --enable-__cxa_atexit
--host=athlon-redhat-linux
Thread model: posix
gcc version 3.3.2 20031022 (Red Hat Linux 3.3.2-1)
compiling NewsCache with "-foptimize-sibling-calls" generates an
executable that dumps core when
starting. Turning on all other (common) optimizers generates a binary
that seems to work fine under
moderate loads. I don't speak C++ so I don't know if this is a
compiler bug or a NewsCache bug.
(On the other hand, -O or -O2 causes a compile error, but that's
almost certainly a compiler bug)
