Trying to use -block optimization fails for me badly.
I have a module, which is very simple - Scheme wise.
It's an interface to offload C-call to pthreads (code here:
http://lists.nongnu.org/archive/html/chicken-users/2010-01/msg00046.html
).
For it's simplicity I picked that one to try the -block optimization.
However the resulting binary fails in a strange way. During the startup
the pthreads module is properly initializsed:
[debug] entering toplevel pool_toplevel...
pthreads.scm:339: g2074
pthreads.scm:341: atomic#set-open-fd!
pthreads.scm:344: thread-wait-for-i/o!
however after all inits are done, I see this:
Error: (semaphore-mutex) bad argument type - not a structure of the
required type #<unbound value> <semaphore>
Call history:
pthreads.scm:294: g2051
pthreads.scm:338: make-thread
pthreads.scm:337: thread-start!
Strange enough, the pthreads module does not at all use the internal
structure of the semaphore at all.
And the same itself is just a normal define-record-type thing.
If I remove the -block switch and recompile pthread.scm all is fine.
Add it back and it breaks again.
So what exactly does -block handle different that -O3 ?
Thanks for any hint!
