Description Ruud van der Pas 2023-05-10 16:56:34 UTC 
For a specific experiment directory, the following error is reported by "gprofng display html":

[Assertion error] get_function_info              - unexpected: number of fields = 10

This error indicates that the input data is not as expected, resulting in an assertion error. As a result, the execution terminates prematurely.

    gprofng: fix 3 bugzillas against gp-display-html
    
    Fix two cases where gp-display-html terminates prematurely because the
    input format is not recognized.  This problem occurs in the function
    overview and caller-callee parts of the code.
    The fix consists of new regular expressions and a different approach
    in handling the input from gp-display-text.
    Also fix a performance problem in the caller-callee part that has a
    noticeable impact on the performance for large applications.
