icewm SIGSEGV

[cgm999]

Hi,

Tried versions 1.7.0.55 and 1.7.0.71 , and both gives SIGSEGV. Version 1.7.0.50 seems to work 798 --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x20} --- 798 +++ killed by SIGSEGV (core dumped) +++

I'm on arch linux (kernel 5.4.54-1-lts ). Let me know what other details you need from me .

Thanks for the offer. Could you run it from valgrind? Like: valgrind /path/to/icewm Maybe first do a git pull and rebuild. It's now at 1.7.0.80.
