Bundled 7.9 Gdb.exe overflows stack when stepping into functions - Repro Case Included

Developer Tools Nsight Visual Studio Edition
1

We are porting a product developed using a reasonably complex commercial C++ engine* for Shield TV.

When stepping into breakpoints using the VisualStudio 2012/2013 Tegra integration, the gdb.exe binary included in the AndroidWorks slows to a crawl and crashes with a stack overflow (looking at the callstack of the crashed gdb.exe in the debugger it appears to be stuck in an infinite recursion).

Using the 7.4.1 precompiled gdb.exe binary from [b][i][u]http://gnutoolchains.com/android[/u][/i][/b] appears to at least be able to step into functions, however it doesn’t seem to catch anything not on the main thread and it doesn’t get variables correctly.

*This issue can be reproduced with the simple example included in the engine. I can provide more info in a PM if required.

I have narrowed this down to a simple test case which can be tested in the NativeApp example provided by the Nvidia visual studio project wizard.

A zip file containing the offending c++ test case plus reproduction instructions as a comment block is located here:

Thanks for the detailed report! We’ve successfully reproduced the issue (on several devices) and will see if it can be fixed for the next release.
