I was curious what the status of the ldap support is in 2.0.5a and where I can get more information on what characteristics this requires in the ldap database. thanks -sv

Just want to remind everyone that we plan to stop using mach_override in asanin favor of OSX's native function interposition. So, we probably don't want to spend too much effort fixing mach_override. --kcc On Fri, Nov 30, 2012 at 4:46 AM, Alexander Potapenko <glider at google.com>wrote: > Looks like this happens on x86_64 because the position of __cxa_throw > is too far from

Looks like this happens on x86_64 because the position of __cxa_throw is too far from the allocated branch island (should be <2G). This can be solved by allocating the branch islands somewhere near the text segment (look for kIslandEnd in asan_mac.cc, this is currently 0x7fffffdf0000) or by patching the function with a longer instruction sequence that stores the jump target in a register and

No, we are not going to use mach_inject. This isn't portable and may be even harder to set up than mach_override. The new ASan runtime will use the dylib interposition and will in fact require DYLD_INSERT_LIBRARIES to work. However ASan already handles it correctly itself: if the corresponding env var is missing the app is just re-execed. Dylib interposition is supported by Apple and should
