Subject: In Rev 1.296 the update of the siglist was moved to the end of ptsignal().
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=3809f4f16c814a20b2d683c19d6ccb94580b5be6;p=openbsd

In Rev 1.296 the update of the siglist was moved to the end of ptsignal().
One atomic_clearbits_int() hiding in SSTOP was missed when converting all
the exceptions that cleared the siglist again. Instead of clearing the bits
the mask needs to be set to 0 so that it is properly ignored.
