OS X hang due to compiler (non)optimizations?
Here's a thought - I haven't encountered the SVN bug that causes
the process to be wedged in rename() since I had a clean rebuild.
The only difference is that I didn't specify a CFLAGS variant of
"-g -Wall" - the default is "-g -O2". So, it's quite possible
that introducing -O2 is covering up this bug.
If it is compiler-related, I've seen reports that Apple is ignoring
bug reports on gcc since they are getting ready to release a
gcc3-based compiler.
So, I'm going to try to rebuild without -O2 and see what happens.
But, as a quick heads-up (perhaps to save me some time), has anyone
compiled svn without -O2 on Darwin? If so, do you not see this
problem? -- justin

If the in-kernel filesystem is hanging, that's a kernel bug, whether or not that's tickled by the compiler's different codegen.
I'm building with the defaults, which may be why I don't see it. I'll try without optimization next time I build. (Got a new laptop, so that should be soonish.)
