Compile
#include <string>
struct QString { static inline QString fromStdString(const std::string &); };
int main() { std::string str; }
using
g++ -g.
Then run
~/bin/gdb-7.0 -ex 'b main' -ex r -i mi --args ./a.out debug
Typing
-stack-list-locals 2
results in
^done,locals=[{name="str",type="QString::string"}]
Note the bogus 'type' field.
Removing the "QString::fromStdString()" and repeating the procedure yields
^done,locals=[{name="str",type="string"}]
as does gdb 6.8 in both scenarios.

It's not 100% reproducible. Every now and then I get the correct answer
"std::string", but in most cases it's "QString::string". This is stock ubuntu
9.04 with gcc (Ubuntu 4.3.3-5ubuntu4) 4.3.3 here.
Archer version is dad6b53fe4a6df586dcd0a57e2151e7663191f18, the 7.0 case is
using a build from an unmodified source package of the gdb 7.0 release.

FWIW, I couldn't reproduce this at all on my F11 box.
I ran gdb under valgrind, on the off chance that this would
show a latent bug, but that didn't report one either.
It is possible that this is something that was fixed by
one of the dwarf2read.c allocation bug fixes; could you
try CVS HEAD?

Andre,
I believe the ball is yours. Are you planning to recheck this?

Thanks for reminding me.
The problem is still reproducible with current git master and released 7.1.
However, I had to go back to gcc 4.2.4 to reproduce it (even the updated Ubuntu
9.04 gcc 4.3 is fine), so this pretty much looks more like a gcc issue than a
gdb issue, and it's even one that is fixed there by now.
I doubt gdb is interested in working around old gcc issues, so I guess this
issue can be closed.
