Please see LEAP.SAI[1,LDE] ( a five line program) for what seems to be
a ridiculously basic Leap bug.

An ENDC followed by an ELSEC gives a non-helpful error message of
ILL MEM REF. (See BADCOM.SAI[1,LDE) for and example.)

Hi. JAM here. I think I have discovered a feature,
but it might well be considered a bug. Try to
compile SAIBUG.SAI[MA,JAM] and it will get an
error on page 8 that says "Not enough params supplied
to procedure". To save you some looking, the statement
P1 is a real, RG1 is an integer. PITCH is a macro defined
on page 4 as:
RGET is defined in LPACK.HDR[MA,JAM] as an integer procedure
of two integer arguements.
NLEND is a macro defined on page 5 as:
PGET is defined in LPACK.HDR[MA,JAM] as an integer procedure
of two integer arguements and one boolean arguement.
What seems to happen is that the terminal ",1" in
the expansion of PITCH seems to get lost. If I put in
REQUIRE "⊂⊃⊂⊃" DELIMITERS; above the call, it gets past that
point. As I say, this may be a feature, not a bug, but here
it is anyway.
