Subject: Recognize signal 151 (SIGLIBRT) sent by gdb.
X-Git-Tag: VALGRIND_3_14_0~281
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ad1c929a82279b166679b65b1dfe93b63f0bf8fb;p=thirdparty%2Fvalgrind.git

Recognize signal 151 (SIGLIBRT) sent by gdb.

It has been observed that gdb on Solaris sends this signal to
child processes. Unfortunately array "pass_signals" was too small
to accomodate this signal and subsequently VG_(clo_vex_control).iropt_verbosity
was overwritten.
This has been fixed now.
