I can't get addr2line to work. I think this is something that's changed
in recent Cygwin releases, because I was using it successfully with an
earlier version (but that was a while ago and I don't have the code I
was using then, so it's possible I was doing something different then
that's escaped my notice now).
Here's the short program I'm using to test it:
 /* demo.c */
 #include <stdio.h>
 void foo() {
 printf("%p\n", __builtin_return_address(0));
 printf("%p\n", __builtin_return_address(1));
 printf("%p\n", __builtin_return_address(2));
 printf("%p\n", __builtin_return_address(3));
 }
 void bar() {
 foo();
 }
 int main() {
 bar();
 return 0;
 }
Compiling and testing this with:
 gcc -g demo.c -o demo
 ./demo|addr2line -e demo.exe
just yields a series of unknowns:
 ??:0
 ??:0
 ??:0
 ??:0
The same test works on Linux, giving the file/line numbers I expect.
I did a full updatbefore testing to make sure I had the latest version
(and searched the list archives for "addr2line"). I'll attach my
cygcheck output in case it's relevant.
