This is very strange. First, the whole purpose of this code is to use dli_fbase offset for the main program. That's why it was added in the first place. PIE binaries can be loaded at any address in memory and the address you see with addr2line or nm or readelf is not the same address you'll see in gdb or in a strack trace. We have to subtract the base address first. But may be openSUSE is different? So, I built on openSUSE Leap and the stack trace was perfectly usable without your patch. I tried both `kill -ABRT` and an artificially introduced memory leak. So I suspect there was some misunderstanding and the problem was somewhere else (I cannot know what, of course, but just as an example - the build was bad and recompilation fixed it).
