https://bugs.winehq.org/show_bug.cgi?id=53063 --- Comment #1 from Zeb Figura <z.figura12(a)gmail.com> --- I somehow managed to get a backtrace just by adding channels. It crashes in ld-linux.so, in tls_get_addr_tail() of all things. Somehow the_map is NULL here: https://sourceware.org/git/?p=glibc.git;a=blob;f=elf/dl-tls.c;hb=glibc-2.33#... Which suggests that somehow glibc data structures are being corrupted? Full backtrace winedbg can get is: =>0 0xf7f7e56f in ld-linux.so.2 (+0x1356f) (0x00000000) 1 0x756b269b in libllvm-13.so.1 (+0x8b769b) (0x7d76f980) 2 0x00000000 (0x7a30212c) 3 0x7587e100 in libllvm-13.so.1 (+0xa83100) (0x7587dfc0) Vastly incomplete, but anyway the glTexSubImage2D() call is coming from match_fbo_tex_update(). -- Do not reply to this email, post in Bugzilla using the above URL to reply.
