I think this is an indication that gcc 3.2-64 bit can't yet produce a 64 bit thread safe binary.
The reasons for the above assumption is that we know that MySQL 4.0 is 64 bit clean as it works without any problems on Linux-Alpha, Linux-Itanium and Solaris 2.8, the last one compiled with Suns 64 bit compiler.
The only way to fix this is to compile MySQL with debugging (configure --with-debug) and run mysqld under a debugger to find out what's going wrong.
I produced a file /tmp/mysqld.trace. It's the InnoDB initialization in 'innobase_init' causing trouble. After the first malloc, the signal 10 (bus error) was sent. Here are the last few lines:
[...] T@1 : >hash_init T@1 : | enter: hash: 10049e0b0 size: 128 T@1 : | >init_dynamic_array T@1 : | | >my_malloc T@1 : | | | my: Size: 2048 MyFlags: 16 T@1 : | | | exit: ptr: 1004c5370 T@1 : | | <my_malloc T@1 : | <init_dynamic_array T@1 : <hash_init T@1 : >innobase_init T@1 : | >my_malloc T@1 : | | my: Size: 23 MyFlags: 16 T@1 : | | exit: ptr: 1004bb340 T@1 : | <my_malloc
I don't know whether it is gcc 3.2 or an InnoDB bug. A recompiled mysql-64bit without InnoDB works, using gcc 3.2 on Solaris 8. Firing up mysql client and playing with SQL commands works, too. In the next days, I will run some stress tests with threads. I expect the thread issues in former gcc 3.x to be gone.
