Call_External on IDL5.0 [message #18678]

Hi -

I have an annoying problem when using call_external on a sunOS
with IDL v 5.0. I call C subroutines.

It works fine if I exit from IDL and recompile from scratch
But if I make a change to the C program and compile it using
cc -G -Kpic -c junk.c
ld -G -o junk.so junk.o

then do
IDL> .r junkcaller
IDL> junkcaller
it gives
Segmentation fault (core dumped) or
Illegal instruction (core dumped)
and crashes IDL.

Then I restart IDL, do the same as above, without changing anything., It
works fine
Has anybody else faced this wierdness ?
I assure you there is no problem with either the code or the
calling because it works fine the second time I do it. It can't be some
cross-referencing
issue because IDL crashes - so the cross referencing can;t be saved.

Thanks for your time, Ranga
