The compiler being used to compile mkstemps.c is broken.=C2=A0 If core dump=
s are
enabled,
you should be able to use gdb (wdb) directly to find the illegal instructio=
n.

If not, one can find the illegal instruction by adding "-save-temps -v" to =
the
compile command.
This will give the information needed to run the compilation under gdb (wdb)

If I was to guess, the illegal instruction is likely to be an out of range
branch.

I would check HP patch for HP ld.=C2=A0 There may be version dependent diff=
erences
in weak support.=
