>Description:
Anytime a second function is being called after a 'next' step, you get "Program received signal SIGTRAP, Trace/breakpoint trap."

I have a very simple testcase. Running the foll commands "break main; run; next; call foo(); call bar()" will cause the SIGTRAP. Note the 'next', as well as 2 calls, is needed to trigger this problem.

This fails in 6.3.0 and 6.3.50. It is ok in 5.3.90.
>How-To-Repeat:
compile bug.cc, and debug with "break main; run; next; call foo(); call bar()"
