ld "undefined reference" shows wrong line number

[Jon Grant <jg at jguk dot org>]

Hello

I noticed in a version of the tools I am using that the output from ld
shows the wrong line number for an "undefined reference". as my tools
are not so recent (codesourcery), would someone be able to confirm if
this issue is reproducable if possible please.

The line number 19 is the last symbol in the start.S. void main(void)
function does exist in the build as well. Possibly is this the debug
info that is incorrect in the start.o file?

I attach my sample assembler file, which is for ARM.

Let me know if you would like me to create a bugzilla ticket.

Best regards, Jon
