@code{g77} sometimes crashes when compiling code
containing the construct @samp{CMPLX(0.)} or similar.
This is a @code{gcc} back-end bug.
It can be worked around using @samp{-fno-emulate-complex},
though that might trigger other, older bugs.
Compiling without optimization is another work-around.
Fixed in @code{egcs} 1.1.

@c Tim Prince discovered this.
Automatic arrays aren't working on HP-UX systems,
Automatic arrays possibly aren't working on HP-UX systems,
at least in HP-UX version 10.20.
Writing into them apparently causes over-writing
of statically declared data in the main program.

or pointers to them being improperly handled,

@c Toon Moene discovered these.
Some Fortran code has been found to be miscompiled
by @code{g77} built on @code{gcc} version 2.8.1
on m68k-next-nextstep3 configurations
when using the @samp{-O2} option.
Even a C function is known to miscompile
on that configuration
when using the @samp{-O2 -funroll-loops} options.
Fixed in @code{egcs}.

A code-generation bug afflicts
Intel x86 targets when @samp{-O2} is specified
compiling, for example, an old version of
the @samp{DNRM2} routine.
The x87 coprocessor stack is being
mismanaged in cases where assigned @code{GOTO}
and @code{ASSIGN} are involved.
Fixed in @code{egcs} version 1.1.

A compiler crash, or apparently infinite run time,

involving @code{COMPLEX} arithmetic

Something about @code{g77}'s straightforward handling of

@item
@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 @code{gcc} back end.
Fixed in @code{egcs} version 1.0.2.
