[Rd] checkRd freezes while parsing erroneous preprocessor macros

I came across with a bug while parsing Rd files.
Given is the following minimal Rd file:
By accident I have a typo at line 6, instead of having #endif I typed #endifd.
If I run checkRd(), parse_Rd(), Rd2HTML(), or others including the command line "R CMD Rconv" R will freeze and the only chance I have is to kill R.
As far as I can tell for checkRd() the problem is the internal function prepare_Rd() which runs for ever.
Is there a way to avoid having that freezing behaviour?
I'm on a Mac running Snow Leopard:
R version 2.14.0 (2011-10-31)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)
attached base packages:
 tools stats graphics grDevices utils datasets methods base
Many thanks in advance,
