https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87015 --- Comment #8 from Jakub Jelinek --- Or if 7.3 works and 8.x doesn't and the two are ABI compatible (dunno about mingw), then you could after you find problematic *.ii file try to bisect which compiler revision changed the behavior and from there you we could try to discover what changed.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87015 Jakub Jelinek changed: What|Removed |Added CC||jakub at gcc dot gnu.org --- Comment #7 from Jakub Jelinek --- If what you are compiling has multiple sources and if e.g. -O0 helps, then you could bisect among the object files to find the problematic *.o file. That can be then preprocessed e.g. with -save-temps. Further analysis can be done by using bisection in the file using #pragma GCC optimize (0) and/or __attribute__((optimize (0))) to find problematic function/method.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87015 Alexandre Oliva changed: What|Removed |Added CC||aoliva at gcc dot gnu.org --- Comment #6 from Alexandre Oliva --- Daniel, since you stated that recompiling with -Og or -O1 did not change the behavior, presumably you could also add -save-temps to the command line. That will produce the preprocessed testcases we need. Getting the command line and the expected output or exit status might be more challenging, and require knowledge of the testsuite at hand, perhaps developers of the library would be willing to help you get the bug report submitted?
