Package: libatomic-ops-dev
Version: 7.3~alpha1+git20120621-1
Severity: serious
Justification: breaks other packages
Hi,
Since the upgrade of libatomic-opts to version 7.3~alpha1+git20120621-1,
firebird2.5 fails to build on ia64. Here are the errors:
g++ -D_FORTIFY_SOURCE=2 -DBOOT_BUILD -I../src/include/gen -I../src/include

To my uneducated eye it seems that the compiler is right: the first argument to
AO_char_fetch_compare_and_swap_acquire is declared as volatile unsigned char*,
while the call from AO_char_compare_and_swap_acquire uses volatile char*.
Thanks for considering,
dam
