Segmentation Fault in compile_keyword_arg
Description
Hi,
I am getting a segmentation fault. The crash occurs in compile_keyword_arg (../compile.c:4604) during argument compilation for the keyword argument assignment.
Minimised test case:
a,b[c:nil]=d
Output:
test.rb: [BUG] Segmentation fault at 0x0000000000000000
