with useNimRtl, unhandled exception cause SIGSEGV

[tommo]

Description

proc call() =
    raise newException(ValueError, "no value")

call()

When compiled with --d:useNimRtl, The program crashed while printing the unhandled exception information.

*maybe related: Also, I encountered a problem that looks like some memory corruption when using --d:useNimRtl. My program consistently crashed at some string operations, after I replaced strutil.% with strformat.&, the problem went away. The same code runs well without --d:useNimRtl. I don't have time to extract the minimal reproducible example at the moment, will revisit this sometime later.
