blocked signals

Reported by: Helmut Eller Owned by: somebody

Component: Core Version: 20c
Keywords: signals interrupts Cc:

Description

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.
  1. Under Linux, cat /proc/<pid>/status shows that SigBlk is 0 i.e. no signals are blocked.
  1. Interrupt the loop with C-c (SIGINT) and wait for the debugger.
  1. SigBlk is still 0.
  1. Type c to continue the loop.
  1. 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.

Fix ticket:55. Copy all of the sigmask instead of just a few. This only affected linux which uses an array for the sigmask.

Note: See TracTickets for help on using tickets.
