            Bug ID: 472963
           Summary: Broken regular expression in configure.ac
    Classification: Developer tools
           Product: valgrind
           Version: 3.21.0
          Platform: Other
                OS: Other
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: jsew...@acm.org

  Target Milestone: ---

SUMMARY
***
A version in hex is read out using dis under Solaris but the regular expression
does not accept hex digits
***

In line 4514 of configure.ac you will find following line which is relevant for
Solaris:

   hex=$( $DIS_PATH -F scf_handle_bind $libscf  | perl -pe '($_) =
/0x(?:4d01)?526570(\d{2}),/' )

This is capturing the last two digits. However “\d” is given where hex digits
may appear. Hence ”\d” is to be replaced by “[0-9a-f]”. 

Observed under Solaris 11.4 on a x86-64 platform.
