Research direction

Open bif.l at line 277 and inspect the conversion from the string value to uint64_t, paying particular attention to Windows integer widths. The issue is done when values larger than 0xFFFFFFFF are converted without corruption using the appropriate function.

Written by the indexing model from the issue text.

Description

On line 277 of bif.l, strtoul is used to convert the value from a string to uint64_t.
However on Windows, unsigned long is 32 bits not 64, so strtoul will silently corrupt any value greater than 0xFFFFFFFF to that value.

The correct function should be strtoull
