Actually, if I just dump the example into a file, compile and install it as a
function, it works.
Only fails when I add the code (without changing anything!) to existing source
where I'd like to use it.
(gdb) next
Single stepping until exit from function _sigtramp,
which has no line number information.
warning: Got an error handling event: "Cannot access memory at address 0x274".
(gdb) next
Single stepping until exit from function reaper,
which has no line number information.
0x004455cf in dyld_stub___error ()
Not sure this is the correct bt, but
#0 0x004455cf in dyld_stub___error ()
#1 0x001abc54 in reaper ()
#2 <signal handler called>
#3 0x96c686fa in select$DARWIN_EXTSN ()
#4 0x001ad801 in ServerLoop ()
#5 0x001af407 in PostmasterMain ()
#6 0x0014c13b in main ()
Looks like something to do with linking. Needle in the haystack I think :(

BTW, I tested the example and it works for me ...
