SIGTRAP on OSX when using CoreFoundation #657

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Compile the test program below
2. Run in it with profiler activated

What is the expected output? What do you see instead?

It should launch the browser with the specified URL.
Instead I get a SIGTRAP

What version of the product are you using? On what operating system?

Tried it on 2.2.1 and 2.2.90 (2.3rc)

Please provide any additional information below.

The backtrace :
