memcheck/tests/manuel1 is failing [FreeBSD 13.0 amd64] #168

Closed paulfloyd closed 2 years ago

paulfloyd commented 2 years ago 
 Syscall param write(buf) points to uninitialised byte(s)
    ...
- Address 0x........ is 4 bytes inside a block of size 131,072 alloc'd
+ Address 0x........ is 4 bytes inside a block of size 32,768 alloc'd

This must be a clang cmov ism where the internal buffer size has shrunk between 12 and 13

Probably safe to filter

The failure was on vbox 13.0 amd64 running on 12.2 amd64 host.

I've since upgraded my machine to 13.o and this testcase passes.
