I don't think any reason that it cannot be done. View Public Profile Find More Posts by .Dare Devil. .Dare Devil. My problem: I trying to analyse a core-dump of "Hello-world" like app that is running on SH4-STLinux, but it fails. In this case this output is sufficient to diagnose the problem: clearly e/d is undefined since the denominator is zero.

  • In a number of cases, I think it would be nice to be able to at least get a stack trace, and examine local variables.
  • It then uses the value in the SP to walk the stack, providing you with a stack trace, and the value of your local variables.

Do not do that, and you should see the backtrace. Instead, it will continue with the stored value represented by a NaN (not a number) or an Inf (infinity) value. e.g. Cannot Access Memory At Address Gdb Backtrace This GDB was configured as "i386-redhat-linux"...
