SBCL crashes while .Net is here #1

Closed Lovesan closed 5 years ago

Lovesan commented 5 years ago

SBCL implementation crashes randomly on Linux should you load .Net Core runtime into a process.

This has something to do with unix signals, most likely, because the usual displayed error is the following:

fatal error encountered in SBCL pid 14564(tid 0x7fc8af4bbb80):
blockables unblocked

The resolution, though hardly defined, is, as you might except, would be, as you would guess - the execution of the tests, with no error, and no crashes, using 'sbcl --script tests.lisp'.

It seems that you can disable signal munging by not passing PAL_INITIALIZE_REGISTER_SIGNALS to https://github.com/dotnet/coreclr/blob/86e600cef40a650a8ffb294dd195186b1679609b/src/pal/src/init/pal.cpp#L302 which is passed by deafault https://github.com/dotnet/coreclr/blob/835836c9d34409af0f31529201dfd57cb2bd053c/src/pal/inc/pal.h#L356

but who knows what that's going to do to their runtime.
