https://bugs.winehq.org/show_bug.cgi?id=47032 Bug ID: 47032 Summary: valgrind reports uninitialized read in writev from call_req_handler Product: Wine Version: 4.6 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: jeffersoncarpenter2(a)gmail.com Distribution: --- Created attachment 64201 --> https://bugs.winehq.org/attachment.cgi?id=64201 Output when running main.exe under valgrind Starting with cloning the source tree $ git clone git://source.winehq.org/git/wine.git $ mkdir wine64_build $ cd wine64_build $ ../wine/configure --enable-win64 $ make $ cd .. $ mkdir test_program $ cd test_program $ echo 'int main() { return 0; }' > main.c $ x86_64-w64-mingw32-gcc main.c -o main.exe $ valgrind --trace-children=yes ../wine64_build/loader/wine64 ./main.exe gives the attached output. The first error appears to be an uninitialized read to writev in request.c (even though it's hard to tell since valgrind is tracing multiple threads). -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=47032 --- Comment #1 from jeffersoncarpenter2(a)gmail.com --- This occurs because the blob mapping->image is set as the reply data, however that struct (pe_image_info_t) contains 4 uninitialized padding bytes. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
