Note: see also the FAQ.txt in the source distribution.
It contains workarounds to several common problems.

If that doesn't help, please report this bug to: valgrind.kde.org

In the bug report, send all the above text, the valgrind
version, and what Linux distro you are using.  Thanks.

Patch to improve C++ stabs parsing

This patch attempts to improve the parsing of C++ stabs. I would be grateful if
you could try it and report on whether it helps. If it doesn't then I wonder if
you can supply any sort of test case for your problem. Thanks.

Comment 3 Nicholas Nethercote 2005-03-01 04:10:32 UTC

What's the status here -- Tom, have you checked in the patch?  Thanks.

Comment 4 Tom Hughes 2005-03-01 09:30:59 UTC

Patch went in on 2004-11-12 but I was waiting for confirmation that it fixed this bug.

Comment 5 Rakesh 2005-03-01 10:08:49 UTC

I had got an un-official patch on top of official valgrind 2.2.0 release from someone that worked for me. I will try the latest version and let you know if it fixes the issue.

Thanks & Regards,
-Rakesh

FYI, I was using following patch till this point of time:

425c425
< static Char *templ_name(Char *p)
---
> static Char *templ_name(Char *p, Bool isName)
460c460

Comment 6 Nicholas Nethercote 2005-07-19 06:04:02 UTC

I'm assuming that Tom's patch fixed this.  Please reopen if it's still a problem.
