Re: Bus error
Hi Eric, Thanks for your email -- the quickest response to a bug report ever! 'locate libsigsegv' turns up nothing. If you have other tests that you would like me to run, please let me know. I'm happy to help where I can.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 [please don't top-post] According to Thomas J. Duck on 12/3/2008 7:29 PM: Hi Eric, Thanks for your email -- the quickest response to a bug report ever! 'locate libsigsegv' turns up nothing. It doesn't turn up anything for me, either, because it is not an executable, but a library. More to the point, you can find out if m4 is using libsigsegv by inspecting your config.log output. For example, when I built a recent development copy of m4, my config.log contains: configure:7054: checking for libsigsegv configure:7082: result: yes configure:7088: checking how to link with libsigsegv configure:7090: result: -lsigsegv and further searching turns up /usr/include/sigsegv.h which includes: #define LIBSIGSEGV_VERSION 0x0204 /* version number: (major8) + minor */ so my machine has libsigsegv 2.4 installed (no known bugs when used on cygwin, but according to the NEWS file, this version is buggy on at least Mac, BSD, and Linux; 2.6 is the most recent release, but even that still has bugs on fringe platforms like Irix that are only fixed in CVS libsigsegv). If you have other tests that you would like me to run, please let me know. I'm happy to help where I can. Are you comfortable using gdb (assuming you have that installed)? Are you able to figure out how to run the failing test under gdb such that you can give a stack trace at the point where the SIGBUS occurred, or would you like a step-by-step walkthrough? - -- Don't work too hard, make some time for fun as well!
