Can anyone confirm this bug?


Thanks,

Comment 1 Richard Biener 2014-08-15 10:04:39 UTC

Confirmed.

Comment 2 Yury Gribov 2014-08-15 14:00:11 UTC

Created attachment 33337 [details]
Short repro

Same on x86_64-unknown-linux-gnu. Memcmp is called with int-typed length parameter which upsets build of POINTER_PLUS_EXPR which expects 64-bit unsigned type. I'm attaching a short repro.

Comment 3 Yuri Gribov 2014-08-19 11:51:43 UTC

This is probably duplicate of #61897 .

Sabrina, could you close if works for you?

Comment 6 Sabrina Souto 2014-09-08 11:33:05 UTC

I checked with the current code in trunk and the test is passing, did you fixed it?
What do you mean by "close"? Change the status for "RESOLVED"?
