Subject: Gdb shows wrong line numbers for the sourcecode
Date: Mon, 20 Jun 2011 17:40:00 -0000	[thread overview]
Message-ID: <20110620173958.GA28683@raven.wolf.lan> (raw)

Hello,

I have built a toolchain for ARM Cortex-M3 based on

binutils-2.20
gcc-4.4.3
gdb-6.0
openocd-0.4.0

With this combination, gdb shows wrong line numbers and wrong lines in the
source listings and in the backtrace like this:

 (gdb) bt
 #0  0x080004a6 in main (argc=536891392, argv=0x20005000) at main.c:45
 (gdb) cont
 Continuing.
 
 Breakpoint 2, 0x080003a4 in send_char (ch=19 '\023') at main.c:45
 45              while (RCC_GetFlagStatus (RCC_FLAG_PLLRDY) == RESET) {
 (gdb) bt
 #0  0x080003a4 in send_char (ch=19 '\023') at main.c:45
 #1  0x080004ca in main (argc=536891392, argv=0x20005000) at main.c:45

In reality, the main function begins at line 91 and the send_char function
begins at line 84. The source code line shown at the breakpoint is a totally
different function.

Any ideas what could cause gdb to get confused?
