Environment:
gcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ./configure : (reconfigured) ./configure
--enable-languages=c,c++,fortran,java,objc --no-create --no-recursion
Thread model: posix
gcc version 4.1.0 20051022 (experimental)
====
Program:
#include <stdlib.h>
int main( int argc, char** argv )
{ abort( );
return 0;
}
====
Compile command:
gcc -O0 -ggdb -o test test.c
====
When run under 'gdb' then using the 'bt' commands results in
#0 0xffffe410 in __kernel_vsyscall ()
#1 0x00afa118 in raise () from /lib/libc.so.6
#2 0x00afb888 in abort () from /lib/libc.so.6
#3 0x080483a5 in main (argc=Could not find the frame base for "main".) at
test.c:4

Works correctly with:
