Hi Piers,
first of all thanks a million for the SAPNWRFC binding you wrote for Ruby. I really appreciate your efforts there. Here in Component Validation we use Ruby for an internal backup tool that helps us archiving and quickly cross-restoring SAP systems (ABAP and JAVA stacks) within our heterogeneous Unix/Linux server environment. Being able to do RFC connects (Unicode!) would really be an additional driving argument pro Ruby.
The gem is working fine so far on Linux, Solaris and HPUX IA64. On AIX however it makes the interpreter crash. While compiling with xlc runs ok with all the NWRFCSDK libs properly linked etc. the Ruby interpreter instantly aborts with an IOT trap (core dumped) when creating an RFC connection handle:
This is what the core file says:
