* [Bug gdb/11639] New: Base class type information not accessible in binaries compiled with g++ 4.5.0 @ 2010-05-26 15:05 andre dot poenitz at nokia dot com 2010-05-26 15:15 ` [Bug gdb/11639] " andre dot poenitz at nokia dot com ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: andre dot poenitz at nokia dot com @ 2010-05-26 15:05 UTC (permalink / raw) To: gdb-prs This is the "second issue" in http://sourceware.org/bugzilla/show_bug.cgi?id=10953 but as it seems unrelated I put it as a separate issue here: If 'Derived' and 'Base' are setup as in #10953, and there is an additional function 'Derived::foo()' with the following implementation void Derived::foo() { Base *b = this; Base &br = *b; } then 'print b' yields "$1 = (void *) 0xbfffee38", i.e. the type information for 'b' is completely lost. It should print (Base *) 0xbfffee38. The problem is not present in g++ 4.4. -- Summary: Base class type information not accessible in binaries compiled with g++ 4.5.0 Product: gdb Version: 7.1 Status: UNCONFIRMED Severity: normal Priority: P2 Component: gdb AssignedTo: unassigned at sourceware dot org ReportedBy: andre dot poenitz at nokia dot com CC: gdb-prs at sourceware dot org GCC build triplet: i486-linux-gnu GCC host triplet: i486-linux-gnu GCC target triplet: i486-linux-gnu http://sourceware.org/bugzilla/show_bug.cgi?id=11639 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 4+ messages in thread

My 4.5 build from GCC svn shows the problem. However, neither the F13 system compiler (which is 4.4-based) nor GCC svn trunk showed the problem. In any case, this doesn't seem to be a gdb bug, so I am closing this. -- What |Removed |Added ---------------------------------------------------------------------------- CC| |tromey at redhat dot com Status|UNCONFIRMED |RESOLVED Resolution| |INVALID http://sourceware.org/bugzilla/show_bug.cgi?id=11639 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 4+ messages in thread
