Subject: Linux i386: tst-bz21269 triggers SIGBUS on some kernels
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=80153017d11b05c6d511951e19379a5942ee6b46;p=thirdparty%2Fglibc.git

Linux i386: tst-bz21269 triggers SIGBUS on some kernels

In addition to SIGSEGV and SIGILL, SIGBUS is also a possible signal
generated by the kernel.

(cherry picked from commit 4d76d3e59d31aa690f148fc0c95cc0c581aed3e8)
