             Bug #: 14729
           Summary: test-tgmath2.c exceeds variable tracking size limit
           Product: glibc
           Version: 2.17
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
        AssignedTo: unassigned@sourceware.org
        ReportedBy: markus@trippelsdorf.de
    Classification: Unclassified


With gcc-4.8 I get (after 1:40 minutes):

test-tgmath2.c: In function âtestâ:             
test-tgmath2.c:93:1: note: variable tracking size limit exceeded with
-fvar-tracking-assignments, retrying without
 test (const int Vint4, const long long int Vllong4)
 ^
test-tgmath2.c:93:1: note: variable tracking size limit exceeded

(gcc-4.6 and gcc-4.7 compile quicker, but the error is the same)

Would it make sense to disabled var-tracking on this test-case?
