[Bug 2059856] Re: [SRU] gdb 10.0 fails to examine any global variables in D programs
Hello Zixing, or anyone else affected, Accepted gdb into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gdb/12.1-0ubuntu1~22.04.3 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-jammy. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: gdb (Ubuntu Jammy) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-jammy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2059856 Title: [SRU] gdb 10.0 fails to examine any global variables in D programs To manage notifications about this bug go to: https://bugs.launchpad.net/gdb/+bug/2059856/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2059856] Re: [SRU] gdb 10.0 fails to examine any global variables in D programs
** Description changed:
- [ Impact ]
+ [Impact]
* GDB 10.0 introduced a regression where it cannot inspect any global
variables in any D programs compiled by any D compiler.
* LDC2 and GDC upstream stated Focal does not have such a problem and stuck
to this release for their test images.
- [ Test Plan ]
+ [Test Plan]
Considering the following D program:
```
module t;
class uv {
int i;
}
__gshared uv i;
int main() {
i = new uv();
return 0; // #break
}
```
If you build it using `gdc -g -O0 t.d -o t` or `ldc2 -o t.o t.d -g`, run
the GDB using the following commands ...
```
b t.d:10
p t.i
```
... you will notice GDB will complain that "'t.i' has unknown type; cast
it to its declared type."
- [ Where problems could occur ]
+ [Where problems could occur]
* The fix consists of a single line change to the demangler. The worst-case
scenario would be breaking the demangling functionality of other programming
languages. However, the newer D ABI uses a symbol mangling scheme that is very
difficult to confuse with other programming languages.
* Incorrect symbol de-mangling may also cause user confusion. However, the
patch fixed a fundamental usability issue.
