Subject: [patch, libfortran] Fix PR 88235, buffer overrun in matmul
Date: Fri, 06 Apr 2018 16:52:00 -0000 [thread overview]
Message-ID: <5fcb79b6-415f-7b0e-7ff3-2bbd5610ad68@tkoenig.net> (raw)
[-- Attachment #1: Type: text/plain, Size: 1714 bytes --]
Hello world,
the attached patch fixes a buffer overrun in matmul, an 8 regression.
No test case since this was only detectable with the address sanitizer
or with valgrind.
Regression-tested on trunk. OK?
Regards
Thomas
