Using it?

[SkewedZeppelin]

I've made a package for Fedora to run with isoalloc globally, however I think I'm doing something very wrong

Testing manually on eb1f3f2 with all defaults:

LD_PRELOAD=/home/admin/isoalloc/build/libisoalloc.so cat /proc/self/maps
#works

LD_PRELOAD=/home/admin/isoalloc/build/libisoalloc.so htop
#works

LD_PRELOAD=/home/admin/isoalloc/build/libisoalloc.so /usr/bin/grep aa
/usr/bin/grep: memory exhausted

LD_PRELOAD=/home/admin/isoalloc/build/libisoalloc.so /usr/bin/meld
[ABORTING][4337](src/iso_alloc.c:1725 _iso_free_internal_unlocked()) Could not find any zone for allocation at 0x2cb1eee57000

LD_PRELOAD=/home/admin/isoalloc/build/libisoalloc.so /usr/bin/firefox
[ABORTING][4493](src/iso_alloc.c:2053 _iso_chunk_size()) Could not find any zone for allocation at 0x389f59ad7000
#I didn't expect this one to work regardless, but still is slightly different error to previous

LD_PRELOAD=/home/admin/isoalloc/build/libisoalloc.so /usr/bin/mumble 
mumble: src/hostapi/jack/pa_jack.c:524: BuildDeviceList: Assertion `err == 0' failed.
Aborted (core dumped)
#this one maybe exposing an actual issue?
#audacity fails the same error

LD_PRELOAD=/home/admin/isoalloc/build/libisoalloc.so /usr/bin/qalculate-gtk 
[ABORTING][5003](src/iso_alloc_util.c:157 mmap_pages()) Failed to mmap rw pages
Aborted (core dumped)

LD_PRELOAD=/home/admin/isoalloc/build/libisoalloc.so /usr/bin/libreoffice 
grep: memory exhausted
/usr/lib64/libreoffice/program/soffice: line 149:  4845 Done                    echo "$checks"
      4846 Aborted                 (core dumped) | grep -q "cc"
[ABORTING][4876](src/iso_alloc_util.c:157 mmap_pages()) Failed to mmap rw pages
Unspecified Application Error
#this one I really don't understand

furthermore enabling MEMCPY_SANITY results in htop segfaulting
and MEMSET_SANITY even segfaults cat

Thanks for the report. I will take a look at reproducing these.

I cannot reproduce the grep, meld, mumble, cat, or htop issues. The others I still need to test. Can you provide more information about versions and which OS you were using?

Updated Fedora 39 with Linux 6.7.x.
Compiled the malloc with clang 17.0.6
