Is there a known memory leak in the CFNetwork function
gzipDecodeData()?
According to Activity Monitor and Instruments, I am losing close to
300 KB of RAM for each 8 MB download through http.
Specifically, the main memory leak is with a call to
CFDataReplaceBytes > __CFDataGrow and there is a smaller one in
__CFDataInit.
CFNetwork not being open source, it is not possible to check the
source code.
A quick search on Google brings back only one occurrence, a crash in
Safari due to a memory issue with gzipDecodeData.
I'm seeing this on Mac OS X 10.6.4, 64-bit process, Foundation tool
(I don't think it's an autorelease issue as it's not some memory I
own that is leaked).
OK, so there is a new memory leak in the networking APIs on Mac OS X
10.6.x :-(
The memory leak does not happen on Mac OS X 10.5.8.
I will file a bug report.
