Segmentation fault on Docker (Alpine only)

[GaetanCathelain]

Hello,

I encountered some issues while trying to use node-libxl on Docker. Whilst I have no issue on non-alpine images, it seems that the readNum() causes a SIGSEGV.

I've created a repo to easily reproduce the issue: https://github.com/GaetanCathelain/libxl-segfault-getnum

I'm unsure as to whether the issue comes from LibXL itself or node-libxl, but my guess is that there are issues with using musl instead of standard libc. Any help would be appreciated
