Summary0037745: Internal Error 200205172 compiling a large unit
DescriptionI have a program that compiles ok, but I get an error during linking:

project1.lpr(81,1) Error: Internal Error 200205172

After spending some time investigating, I've narrowed the error down to a large generated unit with 182k lines. if I start commenting out code, I can eventually get it compile and link at about half that size. It doesn't appear be any specific line in the code - I can comment out different parts of the code.

It links at 21,737,733 bytes. It fails to link at 22,777,193 bytes

Lazarus 2.10 / FPC 3.2.0 on win10, compiling for win64.
Steps To ReproduceGiven that this is a about a large unit, it's not a case of producing a small program to reproduce. Instead:

Grab the master of to a directory called 'markdown' and grab the 'fpc-linking-fail' branch of
to a sibling directory of the markdown directory, and compile the program fhirserver\utilities\freepascal\project1.lpr".

It fails for me, but compiles ok if I disable the define {$DEFINE FHIR_NUTRITIONORDER} on line 61 of fhirserver\library\r2\
TagsNo tags attached.

Please test and close if okay.

Sidenote: next time, please provide a project that doesn't need to be adjusted first. Your project uses absolute paths for the unit directories while relative ones are better and cross platform and the dependency to the markdown project should be done with a Lazarus package.
