[Rd] How to disable R's crash prompt

Dear R devel,

I have a C++ app that calls into embedded R to perform some analytic calculations. When my app encounters a segmentation fault, R always prints the following crash prompt and asks me to enter an action:

Possible actions:

1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace



The problem is my app will be run in non-interactive mode, so there is no way for me to enter the action. Is there a way to disable the crash prompt and have R simply crash the whole app? I have tried using "-file=/dev/null", "-slave", "-vanilla", and pretty much all other start options, to no avail.

Thanks in advance for your help,

Wayne
