Bug ID: 109675
Summary: GCC 13.1: the Modula-2 front-end fails to build on
some platforms
Product: gcc
Version: 13.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: modula2
Assignee: gaius at gcc dot gnu.org
Reporter: gr.audio at gmail dot com
Target Milestone: ---
Happens on any platform on which the 'long unsigned int' type can't hold
a pointer (for instance: Windows/mingw64).
The culprit is this:
../../gcc-13.1.0/gcc/m2/mc-boot/GDynamicStrings.cc: In function 'void
writeAddress(void*)':
../../gcc-13.1.0/gcc/m2/mc-boot/GDynamicStrings.cc:909:18: error: cast from
'void*' to 'long unsigned int' loses precision [-fpermissive]
909 | writeLongcard ((long unsigned int ) (a));
| ^~~~~~~~~~~~~~~~~~~~~~~~
Casting a pointer to a 'long unsigned int' is not exactly portable.
