This allows functions that require an OMF segment byte count of up to 128K to be compiled, although the length in memory at run time is still limited to 64K. (The OMF segment byte count is usually larger, due to the size of relocation records, etc.) This is useful for compiling large functions, e.g. the main interpreter loop in git. It also fixes the bug shown in the compca23 test case, where functions that require a segment of over 64K may appear to compile correctly but generate corrupted OMF segment headers. This related to tracking sizes with 16-bit values that could roll over. This patch increases the memory needed at run time by 64K. This shouldn’t generally be a problem on systems with sufficient memory, although it does increase the minimum memory requirement a bit. If behavior in low-memory configurations is a concern, buffSize could be made into a run-time option.
