memory errors

I am working on a static checking tool that is looking for memory protection errors in R packages. I think I found some in the affxparser package:

• src/R_affx_chp_parser.cpp, in R_affx_ReadCHP, around line 770 should be UNPROTECT(3) instead of UNPROTECT(2) ?
• src/R_affx_chp_parser.cpp, in R_affx_GetCHPEntries, around line 562 should be UNPROTECT(6) instead of UNPROTECT(5) ?

• src/R_affx_chp_parser.cpp, in R_affx_GetCHPGenotypingResults, around line 339 the argument of PrintValue has to be protected

  Rf_PrintValue(mkString("dudey"))

  the temporary string "dudey" could be destroyed within PrintValue before being printed

• the same error around line 348

Thanks @kalibera. I've also seen you're contributions to R core - thanks a bunch. We'll fix this.

Fixed in affxparser 1.41.1 which is now available on Bioc devel.
