We upgraded to 10.1 today and we encountered one issue where
"~_Mutex makes caller exceed speed/space ratio - inlining anyway"
I have attached verbose output of one file for review.
We got around this error by changing only line 141 in xsyslock.h to 'never_inline'.
Any ideas why this might happen, and if our 'fix' is safe (I much prefer not to change library headers)?
If you need any further info please let me know.
