R crash using Sys.which on Windows
This is a change in behaviour of the Windows API function since the code was written (years ago). It will be changed in R 3.1.1: meanwhile you can always use the shortPathName to abbreviate the name.

Dear list,
When installing the latest version of Rtools (3.1.0.1942) into a path that contains more than 96 characters on Windows 7 64-bit,
e.g. into
C:\TheLatestRtoolsInAPathWithMoreThanNinetySixCharactersWillCrashTheRSessionUponCallingTheSysWhichFunctionInRToGetTheGccPath
and assuming that the Rtools bin paths have been appropriately added to the PATH environment variable as in
c:\TheLatestRtoolsInAPathWithMoreThanNinetySixCharactersWillCrashTheRSessionUponCallingTheSysWhichFunctionInRToGetTheGccPath\bin;c:\TheLatestRtoolsInAPathWithMoreThanNinetySixCharactersWillCrashTheRSessionUponCallingTheSysWhichFunctionInRToGetTheGccPath\gcc-4.6.3\bin
the following call from RGui 64-bit (version 3.1.0) reproducibly causes R to crash:
Sys.which("ls")
Sys.which seems to use an internal function on Windows. Is this a known issue?
Please let me know if I can provide any more relevant information.
Best,
Tobias
