Segfault when booting as MSXturboR

[Sanaki]

Observed on x86_64 Linux while attempting to run 10th Frame (1986)(US Gold)(GB).dsk validated against TOSEC dats with the core option bluemsx_msxtype = "MSXturboR". I've gotten a couple slightly different results in the backtrace depending on the core build.

RetroArch build used: libretro/RetroArch@97f3fca139 blueMSX version: cfc1df4d026387883f21994bcce603c4a6be8730

gdb backtrace (buildbot)
