https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D214863 Dimitry Andric <dim@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dim@FreeBSD.org --- Comment #1 from Dimitry Andric <dim@FreeBSD.org> --- This is because g++ 4.9 is now inserting a call to __cxa_throw_bad_array_new_length, e.g.: main: .LFB0: .cfi_startproc leal 4(%esp), %ecx .cfi_def_cfa 1, 0 andl $-16, %esp pushl -4(%ecx) pushl %ebp .cfi_escape 0x10,0x5,0x2,0x75,0 movl %esp, %ebp pushl %ecx .cfi_escape 0xf,0x3,0x75,0x7c,0x6 subl $20, %esp movl $5, -12(%ebp) movl -12(%ebp), %eax addl $2, %eax cmpl $532676608, %eax ja .L2 sall $2, %eax jmp .L5 .L2: call __cxa_throw_bad_array_new_length but the support for this call was only merged to stable/10 in r278724, way after 10.1-R was created. One option is to compile the program without exception support, or to explicitly use gcc 4.8 or lower. I could not find a gcc command line optio= n to disable the generation of these calls. --=20 You are receiving this mail because: You are on the CC list for the bug.=
