The Linux hints file says: # gcc -O3 (and higher) can cause code produced from Storable.xs that # dumps core immediately in recurse.t and retrieve.t, in is_storing() # and last_op_in_netorder(), respectively. In both cases the cxt is # full of junk (and according to valgrind the cxt was never stack'd, # malloc'd or free'd). Observed in Debian 3.0 x86, with gccs 2.95.4 # 20011002 and 3.3, and in Redhat 7.1 with gcc 3.3.1. The failures # happen only for unthreaded builds, threaded builds work okay. "is_stored" and "last_op_in_netorder" have been completely rewritten, and the old hairy context handling code is also gone. I don't see a reason to keep the work around unless it is proven that compiling with -O3 generates bad code yet. On the other hand, it seems I overlooked the HP-UX hints.Thread Previous | Thread Next
