I noticed that a) Thomas' file names are unusually long and 
b) path_conv::set_normalized_path calls cmalloc only for long paths.

Thus I decided to check if the normalized path is correctly freed.
That would explain why cmalloc is returning NULL.
As far as I can see, it isn't freed, at least not all the time. 
When running /bin/ls very_long_path I see 4 allocs and 2 frees.

However I don't find an obvious bug and I don't have the time to pursue
this for the moment.
