This bug may be a dup of Bug#27836 which is queued on the 5.1-engines tree.

Unable to reproduce on G5 PowerMac using either own built sources nor with 64bit 5.1.19-beta pre-built binaries. Joerg will examine if error is reproducable.

It is - happened again in the 5.1.20 builds.

Crash occurs in sql_plugin.cc (gdb) frame 3 #3 0x000000000028ca60 in plugin_dl_add (dl=<incomplete type>, report=<incomplete type>) at sql_plugin.cc:372 372 if (!(plugin_dl.handle= dlopen(dlpath, RTLD_NOW))) (gdb) print &dlpath $2 = (struct <unknown> *) 0xf007e4b0 (gdb) x/s 0xf007e4b0 0xf007e4b0: "/Users/mysqldev/antony/osx-tiger-ppc-64bit/mysql-5.1.20-beta/mysql-test/lib/mysql/some_plugin.so" Arguments to dlopen() are perfectly sane, even if the file does not exist. This appears to be a bug in dyld on MacOS 10.4.6 which has been fixed in later versions, in particular MacOS 10.4.10 definitely doesn't crash in this test.

I have no idea why this was set to "can't repeat". The bug occurs in 5.1.21, 5.1.22, 6.0.3, and 6.0.4 (I just repeated it in 6.0.4-alpha, the others are from existing logs). Assuming 1) it is an OS bug, as claimed above, 2) we still have to build on this version, and 3) we cannot or will not work around it, a "won't fix" (as a conscious decision!) might be appropriate.

This bug does not exist in MacOS 10.4.10 or on MacOS 10.5 - it only exists on 10.4.6 and the crash occurs within the MacOS system libraries. Not a bug in the mysql code. Pushbuild host should be updated from 10.4.6 to 10.4.10. Lars has asked me to reassign this bug.

"Not a bug" because this is a bug in the operating system that is exposed by our binaries, and not a bug in the MySQL Server. As far as I can tell, Mac OS X 10.4.6 was the last version of Mac OS X that was affected. The bug report was originally filed because internal testing on an older version of Mac OS X exposed this bug.
