Re: [Mingw-w64-public] GDB 7.0.1

 However I am sure I'm not the only one encountering this issue. 
 Perhaps I should build my own GDB binary instead, so I have more 
 understanding of what is going on.
I built myself a gdb-7.0.1 release and it still output the warnings

There is a report on the GDB mailing list with someone experiencing
the same issue using RedHat, so it seems to be a bug in GDB itself.

I'm still trying to recreate the issue with a simple test case, and
have yet to do so.

 Hi Kai,

 yes this bug I encounter some time ago, too. It is related to DLL files
 not having any debugging information but are shown in backtrace. Here it
 warns once about psymtab != symtab and code in gdb fix it afterwards. IMHO
 this warning is simply pretty bogus here, or the DLL loader should
 generate for pe-coff the symtab, too.

 Do you mind if I share your findings on the GDB mailing list so as to
 help Tristan Gingold track down what's causing these spurious warnings
 to pop-up?

 Chris

Of course. You can quote me on gdb's ML.

Cheers,
Kai

Re: [Mingw-w64-public] GDB 7.0.1

2010-01-08 Thread Chris Sutcliffe
 Sorry I don't but my compiler is pretty customized I guess it have
 something to do with that.
 Its a multi-lib patched gcc-4_4-branch a cross compiler, don't know if
 it something to do with the config option --with-stabs ?
 But how come you havent been able to encounter the problem, I downloaded
 both 32/64 bits gdb binary you released and both show the same behavior.

Following up on the GDB mailing list, they would prefer an actual
sample which displays the error (Kai's explanation didn't provide
enough guidance).  Is the code you are working on that displays the
issue public domain?  Would it be possible for you to share it so I
can work with the GDB developers to solve the issue?

I've tried creating a simple test case using what Kai had mentioned
about debugging an app that links to a DLL without debugging symbols
and hitting a backtrace, but I have yet to recreate the issue.

Thank you,

Chris
