When setting up SIGPROF signal handler, the

VTune

Profiler

attempts to configure the signals to use the alternative stack size using

sigaltstack()

API to make sure that its signal handler does not depend on the stack size of the profiled application. If the application uses alternative signal stack itself, the

Intel® VTune™

Profiler

requires that the alternative stack size is 64K at a minimum. This may be not the case if the application uses

SIGSTKSZ

constant for the alternative stack size (which is 8192 bytes). In this case, the data collection may terminate with the error message.

Configure the

VTune

Profiler

not to set up the alternative stack and use the stack provided by th application. To do this, pass the following command line options to the tool:

Or, set up the environment variable

AMPLXE_RUNTOOL_OPTIONS=--no-altstack
