R help - Jun 2011 - On .. glibc detected home/sguha/lib64/R/bin/exec/R: realloc(): invalid next size: 0x000000000209e210 ***

Hello,

I'm trying to use rjson to parse a JSON object. The object can be found here

http://pastebin.com/np0s5hgM

(you'll probably need to add quotes around the content)


fromJSON returns the error
 glibc detected home/sguha/lib64/R/bin/exec/R: realloc(): invalid next
size: 0x000000000209e210 ***

Is there a fix coming soon? Maybe CRAN should also have an outstanding
bug field  - packages with unfixed bugs could be removed.


Cheers
Joy


rjson- 0.2.3
and

Saptarshi,

if you look at the sheer number of shared libraries involved, heap 
corruption may have happened due to errors in any of these. 
Finding the reason for such problems is usually difficult, but almost 
impossible without a reproducible example. If you could boil it down 
to a minimal example still triggering the access violation, one could 
try to run it under control of a memory guard like valgrind. 

Best

But rather than posting to this list, you should send a message to the 
package maintainer including reproducible examples. Otherwise the 
package maintainer may not even be aware of any bug nor can he or she 
reproduce.
