[cmucl-ticket] [cmucl] #55: blocked signals

#55: blocked signals --------------------------------+------------------------------------------- Reporter: heller | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: Core | Version: 20c Keywords: signals interrupts | --------------------------------+------------------------------------------- I think there is a problem related to blocked signals and garbage collection: 1. Start {{{cmucl -noinit -eval '(loop (ext:gc :full t))'}}} in a terminal and let it run. 2. Under Linux, {{{cat /proc/<pid>/status}}} shows that !SigBlk is 0 i.e. no signals are blocked. 3. Interrupt the loop with C-c (SIGINT) and wait for the debugger. 4. !SigBlk is still 0. 5. Type c to continue the loop. 6. !SigBlk is now 000000001fc90000 That's a bug, right? It should again be zero. The problem doesn't occur if the loop is empty, so I figure this has something to do with GC. -- Ticket URL: <http://trac.common-lisp.net/cmucl/ticket/55> cmucl <http://common-lisp.net/project/cmucl> Cmucl is a high-performance, free Common Lisp implementation.
