[R] CTRL-C behaviour with RODBC on Solaris2.8
After loading the RODBC package version 1.1-7, Ctrl-C changes its behaviour and is quitting R and returning to the (unix-)command prompt on the solaris2.8 platform here. Here's what happened before and after loading RODBC> for (i in 1:10^5) rnorm(10)^C> library(RODBC) > for (i in 1:10^5) rnorm(10)^C bash-3.00$ platform sparc-sun-solaris2.8 arch sparc os solaris2.8 system sparc, solaris2.8 status major 2 minor 3.1 year 2006 month 06 day 01 svn rev 38247 language R version.string Version 2.3.1 (2006-06-01) This version of R was built with gcc-3.3 (too old?) and ODBC_INCLUDE, ODBC_LIBS pointing to non-standard locations /quant/temp/jagat/usr/local/include, /quant/temp/jagat/usr/local/lib, respectively. Will be glad to provide further details. Any ideas on how to correct this would be greatly appreciated. Thanks -- Jagat K.

This is nothing to do with RODBC, and not reproducible on any of my systems. Investigate your unstated ODBC driver manager and driver for possible causes. Something other than R has uninstalled the signal handler for SIGINT, and a rogue shared library is the likely cause. And please learn to give credit where it is due, instead of blame where it is not. (RODBC attracts far too many careless attributions of blame, this being the second just today. Yet words of thanks are very, very thin on the ground.)

[R] CTRL-C behaviour with RODBC on Solaris2.8
The ODBC driver manager is unixODBC-2.2.11. I will continue investigating other causes and am extremely grateful for the time you took to see if the problem was reproducible on any of your systems. The lack of reproducibility is valuable information to me. Thanks very much again for the time you took to investigate and reply. Thank you very much also to the R project and all the great things it has done. I wouldn't be here without you!
