gcc seems to produce incorrect assembly code when

This isn't a very useful testcase, as I don't have a copy of the chrorus
stdlib.h file. Preprocessed source is more useful for bug reports.
Anyways, there are known problems with the DWARF1 support, it has been
unmaintained for a while, and it has very few if any users. It is
likely to be removed in a future release. The current release 3.3 gives
a warning
tmp.c:0: warning: support for the DWARF1 debugging format is deprecated
The workaround is to use DWARF2 instead. Or alternatively stabs.
