Error: bad immediate value for offset (4100)

[CC me please]

Dear ARM porters,

Could someone please confirm what I see on the armel/buildd:

* https://buildd.debian.org/status/fetch.php?pkg=dcmtk&arch=armel&ver=3.6.8-2&stamp=1705054390&raw=0

Is this a 32bits/limited RAM issue ? Is there a way to fix the symptoms ?

Thanks !

This seems to be caused by stack-clash-protection. Try with:

ifeq ($(DEB_TARGET_ARCH),armel)
export DEB_BUILD_MAINT_OPTIONS = hardening=+all,-stackclash
else

Interestingly, the problem does not affect armhf.

FWIW, while it doesn't affect Debian armhf, it does affect raspbian.

This suggests that it is either a difference between different arm
CPU versions, or a difference between traditional arm (used by Debian
armel and Raspbian) and thumb2 (used by Debian armhf) code generation.
