unexpected behaviour of thread in 1.54

[v.ivanov@…]

Hi

platform: on mac os x 64 bit

running boost thread example from http://www.boost.org/doc/libs/1_54_0/libs/thread/example/thread.cpp with boost version 1.54

results in arch -x86_64 /Users/vivanov/Library/Caches/appCode20/DerivedData/play1-c92f4fc7/Build/Products/Debug/play1 setting alarm for 5 seconds...

Process finished with exit code 139

so the "alarm sounded" line doesnt appear and the thread doesnt sleep for 5 seconds -- instead it quits right after printing "setting alarm for 5 seconds"

the example for 1.49 version runs perfectly with boost version 1.49 works perfectly fine http://www.boost.org/doc/libs/1_49_0/libs/thread/example/thread.cpp

arch -x86_64 /Users/vivanov/Library/Caches/appCode20/DerivedData/play1-c92f4fc7/Build/Products/Debug/play1 setting alarm for 5 seconds... alarm sounded...

Process finished with exit code 139
