Description Dmitry Djachenko 2011-04-29 11:43:18 UTC 
Created attachment 59415 [details]
missing strn*() intercepts (is_overlap() is commented out)

Version:           3.7 SVN (using Devel) 
OS:                Linux

exp-ptrcheck/h_intercepts.c has no support for strncasecmp(), strnpy()

Reproducible: Didn't try


Actual Results:  
==10527== Invalid read of size 16
==10527==    at 0x3A45321EC5: __strcasecmp_l_sse42 (strcmp.S:259)

==10527== Invalid read of size 16
==10527==    at 0x3A4532AA5C: ??? (strcpy.S:94)


Expected Results:  
no errors

memcheck/mc_replace_strmem.c has all required code

similar memcheck's bug was #256600
Comment 1 Dmitry Djachenko 2011-05-04 11:02:40 UTC 
For 3.7.0 exp-ptrcheck will be rewritten
