The new version of binutils allows you to strip debug information and put
it in a separate file. Then you can provide that file to gdb and use it
If I was going to do anything, that is what I would do. I'd just provide
the debug info for the released binaries. This is one of the reasons why
I uploaded a new binutils and gdb recently, in fact.
However, like everything there are two problems 1) lack of tuit cycles and
2) it won't stop people from running gdb on their binaries and reporting
that strdup is causing a problem in mmap. There will still be a "download
the debug info" step no matter what.
