I'm on the x86. This only happens if all three of the following are satisfied
1) -gcoff debugging information is being generated
2) -funit-at-a-time is on
3) -O is on
Turning off -O caused it to work fine. Turning off -funit-at-a-time caused it to work fine. Using a diffrent debugging information format caused it to work fine.
You forgot to say which version of gcc.
Is this maybe http://gcc.gnu.org/PR9963 ?
Also note that -gcoff is not really tested or supported any more, especially
on elf targets. I would not use it at all. stabs or dwarf-2 is more
supported formats. Dwarf-2 support is also in the current version of gcc
for cygwin.
