@item
There seem to be some problems with passing constants, and perhaps
general expressions (other than simple variables/arrays), to procedures
when compiling on some systems (such as i386) with @samp{-fPIC}, as in
when compiling for ELF targets.
@code{g77} sometimes produces invalid assembler code
when using the @samp{-fPIC} option (such as compiling for ELF targets)
on the Intel x86 architecture target.
The symptom is that the assembler complains about invalid opcodes.
This bug is in the gcc back end,
and it apparently occurs only when
compiling sufficiently complicated functions @emph{without} the
@samp{-O} option.
This bug is in the gcc back end.
Fixed in @code{egcs} version 1.1.
