Bug ID: 102030
Summary: private memory overflow in openCL
Product: Mesa
Version: 17.2
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
Assignee: mesa-dev at lists.freedesktop.org
Reporter: janpieter.sollie at dommel.be
QA Contact: mesa-dev at lists.freedesktop.org
Created attachment 133229
--> https://bugs.freedesktop.org/attachment.cgi?id=133229&action=edit
program source
the program is attached, I debugged using the following:
-gdb break 380 & print answer
-investigation of answer[7] and answer[8]
while in both moments of the program they point to exactly the same array, the
content is different. The only thing that happened in between is the
SHA1Init(&ctx), which should not interfere with output[] and k_pad/digest.
