Node 12: "tsc --watch" stops working

[juergenzimmermann]

TypeScript Version:
3.4.5 and 3.5.0-dev.20190425

Search Terms:
typescript watch node 12

Code

tsc --watch

Expected behavior:
No error

Actual behavior:
After upgrading from Node 11 to Node 12 tsc without any option (in addition to tsconfig.json) works as expected. However, tsc --watch produces this output:

#
# Fatal error in , line 0
# Check failed: U_SUCCESS(status).
#
#
#
#FailureMessage Object: 00000093307CD6A0

Playground Link:
Unpack attached testcase.zip, and invoke tsc resp. tsc --watch

Seem to be working correctly

c:\temp\testcase>node -v
v12.0.0

c:\temp\testcase>node node_modules\typescript\lib\tsc.js -v
Version 3.5.0-dev.20190425

c:\temp\testcase>node node_modules\typescript\lib\tsc.js -w
[3:17:03 PM] Starting compilation in watch mode...

I get the same Error on Windows and Linux while using NodeJS 12.

Tested Versions:
3.4.5 and 3.5.0-dev.20190425

Got the same error message:

#
# Fatal error in , line 0
# Check failed: U_SUCCESS(status).
#
#
#
#FailureMessage Object: 0x7ffc98e77040fish: 'tsc --watch' terminated by signal SIGILL

While looking at the syslog (on Linux) I could detect the following message:

kernel: [ 723.962466] traps: node[10648] trap invalid opcode ip:18ad9b9 sp:7fffb11fa018 error:0 in node[400000+2214000]

To me, it appears as if it is a bug inside Node that is somehow triggered by the typescript compiler.

Same as #27379

webpack --watch also has the same issue.

same here on Windows and typescript 3.4.5 with nodejs 12

After upgrading to Node 12.1.0 the issue is gone.
