Hi Paul, I had only a quick glance at your patch. I guess you unintentionally forgot to remove those parts that you already committed for PR110987, along with the finalize-testcases.
I am still trying to find the precise paragraph in the standard you refer to regarding INTENT(OUT) and default initialization. While at it, I think I found a minor nit in testcase pr112407a.f90: component x%i appears undefined the first time it is printed. This can be verified by either adding an explicit x% i = -42 in the main after the allocate(x). Alternatively, running the code with Intel and using MALLOC_PERTURB_ shows a random arg1%i, but is otherwise fine. However, if by chance (random memory) x% i = +42 then the test would likely fail everywhere. Cheers, Harald Am 30.03.24 um 10:06 schrieb Paul Richard Thomas:
Hi All, This bug emerged in a large code and involves possible recursion with a "hidden" module procedure; ie. where the symtree name starts with '@'. This throws the format decoder. As the last message in the PR shows, I have vacillated between silently passing on the possible recursion or adding an alternative warning message. In the end, as a conservative choice I went for emitting the message. In the course of trying to develop a compact test case, I found that type bound procedures were not being tested for recursion and that class dummies, with intent out, were being incorrectly initialized with an empty default initializer. Both of these have been fixed. Unfortunately, the most compact reproducer that Tomas was able to come up with required more than 100kbytes of module files. I tried from the bottom up but failed. Both the tests check the fixes for the other bugs. Regtests on x86_64 - OK for mainline and, in a couple of weeks, 13-branch?
