Try running call_external() function on linux and HP-UX, seperately.
Same C code.
On linux 2.4.9-31, gcc-2.96, IDL 5.4
gcc -c -fPIC -g -Wall test.c to get obj file
ld -shared -o test.so test.o to get lib file
Give "File size limit exceed (core dump)" (.so file is only 38K)
Then jump out of idl.
On HP-UX, IDL 5.3
cc +z -C test.c
ld -b -o test.sl test.o
No problem.
Any hint on why it happens?

What is your external code doing? It sounds like it's creating an output
file somewhere which is larger than is allowed by your limits.
You can see what the maximum allowed file size is by using the command
'ulimit -f'.
