This bug is (still) present in 5.0.8 beta. So no, not fixed, and should not be closed. Things like this (and thinking of how long it took to fix the NPTL vs. LinuxThreads issue) really turn me off of mysql. For a good understanding -- that is my loss too. Thanks for your time. bjd

what bug is not fixed ? could you report it separately please ? (it must be a different bug, because this bug - 7851 - *is* fixed, I see the fix in the source)

ehm, sorry. Ramil, could you remove #if defined(__ia64__) from your patch please ? :)

I am using gnu tools: gccversion='3.4.3', gnulibc_version='2.3.3'. How to repeat: Compile with kernel 2.6.10+ using current gcc+glibc. Suggested fix: I can't understand how 'new' is confusing the plain c kernel headers. I cannot find any mysql problem - this is possibly a gnu-gcc problem ( they say no ). My workaround is to patch asm/system.h: sed -i "s/new/nneww/g" /usr/include/asm/system.h ( my kernel headers are put there after kernel compiles ).
