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:
*** caught segfault ***
address 0x8, cause 'memory not mapped'
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
R does not do that in 'non-interactive mode'. Take a look at the
code: that section is conditional on R_Interactive.
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.
They do not control if R is interactive: the front-end (yours, I
presume since you mention embedding but do not otherwise give any
details) does.
Thanks in advance for your help,
Wayne
