Optimized compile of serialise/Failures causes abort on x86 #1576

dipinhora · 2017-02-11T20:53:01Z

Compiling/running the tests for the Serialise package results in an abort if the tests are compiled without debug with ponyc. This happens on both config=debug and config=release builds of ponyc. Additionally, this seems independent of llvm versions.

The following snippet shows what occurs:

It looks a lot like what @Praetonus describes in #1186 (comment)

Maybe a duplicate.

SeanTAllen · 2017-06-07T20:17:20Z

@Praetonus agrees that this looks like #1186.

…lang#1576

…ng#1576

SeanTAllen · 2018-06-06T01:31:51Z

@dipinhora is this still an issue?

dipinhora · 2018-06-06T02:52:38Z

Still a segfault. But with a slightly different stack trace (see below). I tried with both llvm-3.9 and llvm-6.0. Same results.

The following snippet shows what occurs:

Possibly related... As of current master both regex/Regex.groups and net/http/_HTTPConnection._new_conn also segfault. However, their backtraces seem to be corrupt.
