Re: building with debugging turned on

OK - almost there...

I keep getting the following, which is preventing me from actually  
running any of my test routines.

Standard ML of New Jersey v110.57 [built: Mon Nov 21 09:35:29 2005]
- CM.make("clapack.cm");

everything proceeds normally, and then :

[plugin $/make-tool.cm loaded successfully]
[make -f clapack.make SMLNJ_BINDIR=/usr/local/smlnj-110.57/bin FFI/ 
clapack.cm]
make: `FFI/clapack.cm' is up to date.

uncaught exception SysErr [SysErr: Interrupted system call [intr]]
   raised at: <waitpid.c>
              Basis/Implementation/Unix/os-process.sml:47.38-47.40
              ../cm/util/safeio.sml:41.55
              ../cm/tools/main/private-tools.sml:533.13
              ../cm/util/safeio.sml:41.55
              ../cm/util/safeio.sml:41.55
              ../cm/parse/parse.sml:501.47

Do I need to create my program as a heap image and load it instead of  
sml ?
