#1045 bug in rxregexp when using alternatives

[Anonymous]

given str1 = " AA2012 " and str2 = " BB2012 "
the following regexp finds a hit in str2 but is failing to find a hit in str1
RE1 = "(AA|BB)[:SPACE:]*[:DIGIT:]"

however the following equivalent regexp does find a hit in both str1 and str2:
RE2 = "(AA[:SPACE:]|BB[:SPACE:])[:DIGIT:]"

testcase attached.

Hi,

Thanks for attaching a test program, especially an actual working test group.

I'll take a look at this, but I don't understand the reg expr code that well, I might not be able to do anything about it.

Committed code fix with revision [r11336].
Also added test cases, and made a minor rexxref update (the latter requiring another fix with [r11337]).
