Source info for PSPromotionManager methods is not shown on fastdebug build on Linux-amd64:

I thought that it could be caused by the fact that one of these methods is inline and other is template, but source info for should_scavenge exists while it is template method defined as 'inline':

[2012-06-20T14:58:29.01] gdb> #6 0x00002acea8d23eca in should_scavenge<narrowOop> (

Issue could be reproduced with JDK 7u6-b13-fastdebug.
