+// Regression test for #87481: short backtrace formatting cut off the entire stack trace.
+
+// Codegen-units is specified here so that we can replicate a typical rustc invocation which
+// is not normally limited to 1 CGU. This is important so that the `__rust_begin_short_backtrace`
+// and `__rust_end_short_backtrace` symbols are not marked internal to the CGU and thus will be
+// named in the symbol table.
+// compile-flags: -O -Ccodegen-units=8

+// run-fail
+// check-run-results
+// exec-env:RUST_BACKTRACE=1
+
+// We need to normalize out frame 5 because without debug info, dbghelp.dll doesn't know where CGU
+// internal functions like `main` start or end and so it will return whatever symbol happens
+// to be located near the address.
+// normalize-stderr-test: "5: .*" -> "5: some Rust fn"

+// Backtraces are pretty broken in general on i686-pc-windows-msvc (#62897).
