+ to deprecated_inside_entry_file destroys a meaningful backtrace
+ under some conditions. E. g. the backtrace tests in the asm-source
+ testcase are broken for some targets. In this test the functions
+ are all implemented as part of one file and the testcase is not
+ necessarily linked with a start file (depending on the target).
+ What happens is, that the first frame is printed normaly and
+ following frames are treated as being inside the enttry file then.
+ This way, only the #0 frame is printed in the backtrace output.''

Gdb also supports an alternate method to avoid running off the bottom
of the stack.
