when issuing `make -j1`

[morgan-greywolf]

I find that I can work around the issue by issuing CFLAGS=-Wno-lto-type-mismatch make -j1 instead of make -j1 in the source folder.

Thanks. I don't think you have to add any options. I'll make the fix.

[stsp]

But thanks for info: that helps me figure I need -flto to reproduce.

[stsp]

Should now be fixed.

[morgan-greywolf]

Confirmed as working.
