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.
