SIGBUS error

ASR — Wed, 20 Apr 2011 17:26:43 GMT

Attached program throws SIGBUS error when we changed to most private address space g++. Not able to debug with gdb because of Error trying to get information about dynamic linker.

# g++ -N -Xlinker +as -Xlinker mpas -g -pthread mmapfile.cxx
# ./a.out
Bus error(coredump)

You have the core but can't analyze it? You'll need a hex editor. You can also get some info with 'strings core'.

And your cxx file is very unreadable. What the hell is a cxx file anyway? Can't you put this into ascii text format with notepad or something?

This works fine with aC++ and g++ 4.2.1.

What version of gdb do you have?

Better to get a gdb that works.

>You can also get some info with 'strings core'.

Not likely.

A C++ source file.
