Hi, i can't upgrade php to the last 7.3 version on two vps with 512 mb ram (they used to be 1gb ram but i decided to downgrade the plan since).

I'm getting this errors during php compiling:

Code:

 /svr-setup/php-7.2.9/sapi/phpdbg/phpdbg_watch.c -o sapi/phpdbg/phpdbg_watch.lo
{standard input}: Assembler messages:
{standard input}:396092: Warning: end of file not at end of a line; newline inserted
{standard input}:397604: Error: unknown pseudo-op: `.lbe'
{standard input}: Error: open CFI at the end of file; missing .cfi_endproc directive

and then:

Code:

gcc: internal compiler error: Killed (program cc1)
