The infinite loop happens if chunk_alloc_arena needs to be called when a0malloc is called. It in turn calls chunk_alloc_default, which uses tsd, which calls a0malloc if it's the first time the tsd is being gotten from the current thread. tsd only uses a0malloc on platforms where there is no native thread local storage support, which, for Mozilla, essentially means anything that is not Linux. But the tsd is only neededto get the dss precedence setting of the given arena. That setting has no effect when dss is disabled, which it is on Windows and Mac. Moreover, the default setting for dss precedence is "secondary", which means jemalloc only tries dss after it failed to get memory with mmap/VirtualAlloc. Considering the cases where mmap/VirtualAlloc would fail essentially means there is shortage of address space, sbrk() is not going to have much more success, so we might as well disable dss support on all platforms, avoiding the infinite loop problem on Android and B2G as well. |

project pages with documentation can be found at:
https://developer.mozilla.org/en/Mozilla_Source_Code_Directory_Structure
For information on how to build Mozilla from the source code, see:
http://developer.mozilla.org/en/docs/Build_Documentation
To have your bug fix / feature added to Mozilla, you should create a patch and
submit it to Bugzilla (https://bugzilla.mozilla.org). Instructions are at:
http://developer.mozilla.org/en/docs/Creating_a_patch
http://developer.mozilla.org/en/docs/Getting_your_patch_in_the_tree
If you have a question about developing Mozilla, and can't find the solution
on http://developer.mozilla.org, you can try asking your question in a
mozilla.* Usenet group, or on IRC at irc.mozilla.org. [The Mozilla news groups
are accessible on Google Groups, or news.mozilla.org with a NNTP reader.]
You can download nightly development builds from the Mozilla FTP server.
Keep in mind that nightly builds, which are used by Mozilla developers for
testing, may be buggy. Firefox nightlies, for example, can be found at:
