Subject: Print a stack trace as part of the "unhandled instruction bytes" warning.
X-Git-Tag: svn/VALGRIND_3_7_0~699
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4f4749956f3f5211a47dc33ad14561c1c5e70c02;p=thirdparty%2Fvalgrind.git

Print a stack trace as part of the "unhandled instruction bytes" warning.
Useful if the program in question catches signals, in which case the usual
"Process terminating..." stack trace isn't shown.  Requested by Jesse
Ruderman.
