@hzongaro : please investigate

[hzongaro]

It looks like when I introduced the _suppressEA field in OMR::Options, I failed to ensure that the field was initialized to NULL in OMR::Options::init.

The call to SimpleRegex::match should only occur if _suppressEA is non-NULL, so this crash is almost certainly due to the fact that the field is uninitialized.

I'm running a personal build with a fix, and I will then open a pull request. I think the fix should also go into the v0.38.0-release.

[pshipton]

Reopen until the fix is delivered to the release stream(s).

[pshipton]

@hzongaro do you know the change which introduced the problem?

[pshipton]

I found eclipse-openj9/openj9-omr@a7a2d03748b.
Looks to affect all current releases, 23_02, 0.37, 0.38.

Peter @pshipton, that's right. Should I open pull requests against 0.37 and 23_02, in addition to the pull request for 0.38.0 that I've already opened?

[pshipton]

Yes pls do.

[hzongaro]

Fixes have been merged on all current branches.
