C++Builder XE10.2 [ilink32 Error] Fatal: Exceeded memory limit for block Line number cache in module <somethingsomething.cpp>

Completely stuck on linking stage, when migrating group of projects to C++Builder XE10.2.
Win32 target, clang compiler.

The module, which causes ilink32 to fail with abovementioned error, uses boost::spirit classic.
What is puzzling, is that another project from the same group passes linking OK, while using boost::spirit as well, with much more complex grammar, and much bigger code inside.

Is there any way to control ilink32 heaps through cmdline, or configuration file(s)?

The linker dump is as follows:

In my experience, the only solution is to either reduce the amount of code in the module or disable debugging symbols. If the former isn't an option, you can disable debugging symbols for just the file in question rather than the entire project. At the top of the file, add the following:

#pragma option push
#pragma option -v- -y- 

...and at the bottom of the file, add:

#pragma option pop
