digitalmars.D.bugs - [Issue 14607] New: dmd crashes intermittently when building in 32


          Issue ID: 14607
           Summary: dmd crashes intermittently when building in 32 bit
           Product: D
           Version: D2
          Hardware: x86
                OS: Mac OS X
            Status: NEW
          Severity: major
          Priority: P1
         Component: DMD
          Assignee: nobody puremagic.com
          Reporter: andrei erdani.com

I've been spending a fair amount of time on this, thinking the problem is with
the D program; I'd been using -run to run after compilation, but compiler
crashes even without -run. The command line is:

../dmd/src/dmd -conf= -I../druntime/import  -w -dip25 -m32  -g -debug -main
-unittest generated/osx/debug/32/libphobos2.a -defaultlib= -debuglib= -L-lcurl
-cov std/experimental/allocator/affix_allocator.d

On OSX it sometimes works, sometimes (about one in 10 times) crashes. The crash

segmentation fault  ../dmd/src/dmd -conf= -I../druntime/import -w -dip25 -m32
-g -debug -main

dmd(38716,0x7fff709b1300) malloc: *** error for object 0x101a37208: incorrect
checksum for freed object - object was probably modified after being freed.

I'm using the master dmd as of right now. Will get back when I have a reduced
test case.
